Technology Previews, see Section 2. Packages that require vware additional customer contract, see Section 2. Some packages shipped as part of the frre Workstation Extension are L2-supported only.

Packages with names ending in -devel vmware workstation 14 release notes free header files and similar developer resources will only be supported together with their main packages.

SUSE will only support the usage of original packages. That is, packages that are unchanged and not recompiled. To learn about supported features and limitations, refer перейти the vmware workstation 14 release notes free sections in this document:. Section 5. Check the workwtation status of individual packages using the RPM metadata that can be viewed with rpmzypper windows 10 free, or YaST.

Technology previews are packages, stacks, or features delivered by SUSE to provide glimpses vmware workstation 14 release notes free upcoming innovations. Technology previews are included for your convenience to give you a chance to test new technologies within your environment.

We would appreciate your feedback! If you test a technology preview, contact your SUSE representative and let them know about tree experience and use cases. Your input is helpful for future development. Technology previews are still in development. Therefore, they may be functionally incomplete, free games ninja turtles for pc, or in other ways not suitable for production use.

Technology previews may only vmware workstation 14 release notes free available for specific hardware architectures. Details and functionality of technology previews are subject to change. As a result, upgrading to subsequent releases of a technology preview may be impossible and require a fresh installation.

Technology previews can be removed from a product at any time. This may be the case, for example, if SUSE discovers that a preview does not meet the customer or market needs, or does not comply with enterprise standards. It was introduced in the Linux kernel version 4.

Notws optimization is only available in Linux note version 4. You can enable it by adding the i So in this case, use i The command to add the option to the bootloader configuration would then be:. Traditionally, zypper executes the rpm notea separately for each operation in a transaction. This is among other things a lot slower for a large number of packages.

Therefore we have implemented a new backend that runs all the operations in a single transaction using librpm. Because this feature is offered as a technology preview, enabling it system-wide notees known to have issues, thus we recommend enabling vmware workstation 14 release notes free feature per workatation, for example:. Same as the default kernel flavor, it does not use preemption.

Main purpose at this time is to allow for side-by-side benchmarking for High Performance Computing, Machine Learning and other Big Data use cases. Contact your SUSE representative if you notice performance gains for your specific workloads. See Section 5. After notrs the 64K kernel, any swap partitions need to re-initialized to be usable.

To do this, run the swapon command with the –fixpgsz parameter on the swap partition. Note nottes this process deletes data present in the swap partition for vmware workstation 14 release notes free, suspend data. Together they can avoid the need for third-party drivers and microsoft office 2019 professional plus edition for windows 10 free download. To use them, the Device Tree passed by the bootloader to the kernel needs to include a description nites the Vivante GPU for the kernel driver to get loaded.

You may need to contact your hardware vendor for a bootloader firmware upgrade. To use them, the Device Tree passed by the bootloader to the kernel needs to include a description of the Mali GPU for vmware workstation 14 release notes free kernel driver to get loaded. This allows its commands ls and load vmware workstation 14 release notes free access files on Btrfs-formatted partitions on supported boot media, such as microSD and USB. This means vmwaer currently it has to be explicitly enabled.

This can be done in the following ways:. This release provides an enhanced support of Wayland as well as providing X applications on Wayland via XWayland with 3D acceleration. See the full changelog for mvware details. It is shipped as technology preview. Http://replace.me/16098.txt GUI will not allow the feature to be enabled for a guest that is already installed nor can it be turned off for a guest that was installed with the feature enabled.

The keylime package provides an end-to-end solution for utilizing TPM technology to provide remote trust. The keylime package is offered as a technical preview. Modules and extensions add functionality to the system. For more information about all package and module changes since the last version, see Section 2. Vmware workstation 14 release notes free module has a clearly defined scope.

Modules differ in their life cycles and vmwate timelines. SLE Extensions add extra functionality to the system and require their own registration key, usually at additional cost. The following extension is not covered by SUSE support agreements, available at no additional cost and without an extra registration key:. This sections lists derived and related products. However, they do not document the installation procedure itself.

Ссылка set of media has changed with 15 SP2. There still reelease two different installation media, but the way they can be used has changed:.

Vmware workstation 14 release notes free


When VMware Horizon is used with the Blast Extreme display protocol, frame buffer consumption increases over time after multiple disconnections from and reconnections to a VM.

This issue occurs even if the VM is in an idle state and no graphics applications are running. Computer Management shows problems with the primary display device. After multiple VMs configured with vGPU on a single hypervisor host are migrated simultaneously, the remote desktop session freezes with an assertion failure and XID error It does not occur if only a single VM is migrated.

The rebuild of the driver fails because the compiler version is incorrect. Any attempt to reinstall the driver fails because the kernel fails to build. Stop and restart the Xorg service and nv-hostengine on the ESXi host. Wait for 1 second to allow nv-hostengine to stop. When vMotion is used to migrate a VM configured with vGPU to another host, users’ sessions may freeze for up to several seconds during the migration.

Administrators can mitigate the effects on end users by avoiding migration of VMs configured with vGPU during business hours or warning end users that migration is about to start and that they may experience session freezes. End users experiencing this issue must wait for their sessions to resume when the migration is complete.

When a VM configured with vGPU is migrated to another host, the migration stops before it is complete. After the migration stops, the VM is no longer accessible. This issue occurs if the ECC memory configuration enabled or disabled on the source and destination hosts are different. The ECC memory configuration on both the source and destination hosts must be identical. Reboot the hypervisor host to recover the VM.

Before attempting to migrate the VM again, ensure that the ECC memory configuration on both the source and destination hosts are identical. Even with this patch, migration of a VM configured with vGPU requires the ECC memory configuration on both the source and destination hosts to be identical.

When a VMware Horizon session with Windows 7 is connected to four displays, a black screen is observed on one or more displays. This issue occurs because a VMware Horizon session does not support connections to four 4K displays with Windows 7. For example, host CPU utilization when only a small number of VMs are running is as high as when several times as many VMs are running. Because of a known limitation with NvFBC, a frame capture while the interactive logon message is displayed returns a blank screen.

An NvFBC session can capture screen updates that occur after the session is created. Before the logon message appears, there is no screen update after the message is shown and, therefore, a black screen is returned instead. This default setting enables 2D DirectX applications such as Microsoft Office to use software rendering, which can be more efficient than using the GPU for rendering.

Change the local computer policy to use the hardware graphics adapter for all RDS sessions. Set the Use the hardware default graphics adapter for all Remote Desktop Services sessions option.

The error stack in the task details on the vSphere web client contains the following error message:. Increase the maximum switchover time by increasing the vmotion. This behavior is a result of the mechanism that is used to measure GPU engine utilization. The command nvidia-smi vgpu -m shows that vGPU migration is supported on all hypervisors, even hypervisors or hypervisor versions that do not support vGPU migration.

Depending on the combination of options set, one of the following error messages is seen when the VM is powered on:. This message is seen when the following options are set:. When nvidia-smi is run without any arguments to verify the installation, the following error message is displayed:.

In some situations, after the VM is powered on, the guest OS crashes or fails to boot. When windows for 3D applications on Linux are dragged, the frame rate drops substantially and the application runs slowly.

On Red Hat Enterprise Linux 6. Disabling the GUI for licensing resolves this issue. To prevent this issue, the GUI for licensing is disabled by default. In environments where non-persistent licensed VMs are not cleanly shut down, licenses on the license server can become exhausted. For example, this issue can occur in automated test environments where VMs are frequently changing and are not guaranteed to be cleanly shut down.

The licenses from such VMs remain checked out against their MAC address for seven days before they time out and become available to other VMs. If VMs are routinely being powered off without clean shutdown in your environment, you can avoid this issue by shortening the license borrow period. To shorten the license borrow period, set the LicenseInterval configuration setting in your VM image. Memory exhaustion can occur with vGPU profiles that have Mbytes or less of frame buffer.

The root cause is a known issue associated with changes to the way that recent Microsoft operating systems handle and allow access to overprovisioning messages and errors. If your systems are provisioned with enough frame buffer to support your use cases, you should not encounter these issues.

Additionally, you can use the VMware OS Optimization Tool to make and apply optimization recommendations for Windows 10 and other operating systems. If you do not change the default graphics type you will encounter this issue. When memory usage is monitored from inside the VM, no memory usage alarm is shown. For VMware vSphere releases before 6. Any attempt to install the driver on a VM on a host in an automated DRS cluster fails with the following error:. Ensure that the automation level of the DRS cluster is set to Manual.

Click Apply to accept the configuration. The additional vGPU devices are present in Windows Device Manager but display a warning sign, and the following device status:. This is not a currently supported configuration for vGPU.

If multiple VMs are started simultaneously, vSphere may not adhere to the placement policy currently in effect. Sleep is not supported on vGPU and attempts to use it will lead to undefined behavior. Installing the VMware Horizon agent will disable the Sleep option. For example, on a server configured with G of memory, these errors may occur if vGPU-enabled VMs are assigned more than G of memory. Reduce the total amount of system memory assigned to the VMs. On a system running a maximal configuration, that is, with the maximum number of vGPU VMs the server can support, some VMs might fail to start post a reset or restart operation.

The GPU utilization remains high for the duration of the Horizon session even if there are no active applications running on the VM.

Issues occur when the channels allocated to a vGPU are exhausted. VM failures or crashes on servers with 1 TiB or more of system memory. VMs configured with large memory fail to initialize vGPU when booted. Windows R2 licensed clients cannot acquire licenses from a DLS instance.

VM fails after a second vGPU is assigned to it. When a licensed client deployed by using VMware instant clone technology is destroyed, it does not return the license. A licensed client might fail to acquire a license if a proxy is set.

Disconnected sessions cannot be reconnected or might be reconnected very slowly with NVWMI installed. Windows VM crashes during Custom Advanced driver upgrade. NVML fails to initialize with unknown error. Citrix Virtual Apps and Desktops session corruption occurs in the form of residual window borders.

Suspend and resume between hosts running different versions of the vGPU manager fails. On Linux, a VMware Horizon 7. On Linux, the frame rate might drop to 1 after several minutes.

Remote desktop session freezes with assertion failure and XID error 43 after migration. Citrix Virtual Apps and Desktops session freezes when the desktop is unlocked. Black screens observed when a VMware Horizon session is connected to four displays. Host core CPU utilization is higher than expected for moderate workloads. Frame capture while the interactive logon message is displayed returns blank screen. VMware vMotion fails gracefully under heavy load.

View session freezes intermittently after a Linux VM acquires a license. When the scheduling policy is fixed share, GPU utilization is reported as higher than expected. GPU resources not available error during VMware instant clone provisioning. Tesla P40 cannot be used in pass-through mode. On Linux, 3D applications run slowly when windows are dragged.

Licenses remain checked out when VMs are forcibly powered off. ESXi 6. Updates in Release Hardware and Software Support Introduced in Release Feature Support Withdrawn in Release Red Hat Enterprise Linux 7. The base VMware vSphere 7. Tesla M10 vCS is not supported.

Tesla M60 vCS is not supported. Note: To determine the total BAR1 memory, run nvidia-smi -q on the host. Supported Management Software and Virtual Desktop Software Releases This release supports the management software and virtual desktop software releases listed in the table.

Releases earlier than 6. Limitations Only direct connections are supported. NVSwitch is not supported. Only time-sliced vGPUs are supported. PCIe is not supported. SLI is not supported. Note: Unified memory is disabled by default. If used, you must enable unified memory individually for each vGPU that requires it by setting a vGPU plugin parameter.

Therefore, if the creation of VM templates includes driver installation, the template should be created from a VM that is configured with a supported GPU while the driver is being installed. The H. Total frame buffer for vGPUs is less than the total frame buffer on the physical GPU Some of the physical GPU’s frame buffer is used by the hypervisor on behalf of the VM for allocations that the guest OS would otherwise have made in its own frame buffer.

For example, these issues may occur with the Adobe Photoshop and LuxMark OpenCL Benchmark applications: When the image resolution and size are changed in Adobe Photoshop, a program error may occur or Photoshop may display a message about a problem with the graphics hardware and a suggestion to disable OpenCL. Workaround Use a profile that supports more than 1 virtual display head and has at least 1 Gbyte of frame buffer. Reboot the server. A guest VM driver is incompatible with the current release of Virtual GPU Manager in either of the following situations: The guest driver is from a release in a branch two or more major releases before the current release, for example release 9.

Disabling vGPU. Code Note: This setting can only be changed when the VM is powered off. Resolved Issues Only resolved issues that have been previously noted as known issues or had a noticeable user impact are listed.

Issues Resolved in Release This issue occurs if the nvidia-gridd service cannot resolve the fully qualified domain name of the license server because systemd-resolved.

When this issue occurs, the nvidia-gridd service writes the following message to the systemd journal: General data transfer failure. Couldn’t resolve host name. Known Issues 5. Status Open. When memory allocation fails, the error messages that are written to the log file on the hypervisor host depend on the hypervisor. Workaround If an application or a VM hangs after a long period of usage, restart the VM every couple of days to prevent the hypervisor host from running out of memory.

GPU When this issue occurs, the following error message is written to the vmware. Any attempt to power on a second VM fails with the following error message: Insufficient resources. At least one device pcipassthru0 required for VM vm-name is not available on host. Version This issue affects migration from a host that is running a vGPU manager 11 release before Workaround Upgrade the host that is running a vGPU manager 11 release to release When this issue occurs, the following messages are written to the log file on the hypervisor host: T When a licensed client deployed by using VMware instant clone technology is destroyed, it does not return the license Description When a user logs out of a VM deployed by using VMware Horizon instant clone technology, the VM is deleted and OS is not shut down cleanly.

Workaround Deploy the instant-clone desktop pool with the following options: Floating user assignment All Machines Up-Front provisioning This configuration will allow the MAC address to be reused on the newly cloned VMs.

Workaround Perform this workaround on each affected licensed client. On Linux, restart the nvidia-gridd service. Status Closed. This issue is accompanied by the following error message: This Desktop has no resources available or it has timed out This issue is caused by insufficient frame buffer.

Workaround Ensure that sufficient frame buffer is available for all the virtual displays that are connected to a vGPU by changing the configuration in one of the following ways: Reducing the number of virtual displays.

When this issue occurs, the following error message is seen: Insufficient resources. One or more devices pciPassthru0 required by VM vm-name are not available on host host-name. A Volatile Uncorr. MIG M.

Workaround Stop the nvidia-gridd service. Try again to upgrade the driver. Citrix Virtual Apps and Desktops session corruption occurs in the form of residual window borders Description When a window is dragged across the desktop in a Citrix Virtual Apps and Desktops session, corruption of the session in the form of residual window borders occurs.

Suspend and resume between hosts running different versions of the vGPU manager fails Description Suspending a VM configured with vGPU on a host running one version of the vGPU manager and resuming the VM on a host running a version from an older main release branch fails. Version This issue affects deployments that use VMware Horizon 7. Workaround Use VMware Horizon 7. Workaround If necessary, stop the Xorg server. Start the Xorg server.

Frame buffer consumption grows with VMware Horizon over Blast Extreme Description When VMware Horizon is used with the Blast Extreme display protocol, frame buffer consumption increases over time after multiple disconnections from and reconnections to a VM.

Workaround Reboot the VM. Version This issue affects Windows 10 , and VMs. Remote desktop session freezes with assertion failure and XID error 43 after migration Description After multiple VMs configured with vGPU on a single hypervisor host are migrated simultaneously, the remote desktop session freezes with an assertion failure and XID error Version Microsoft Windows 10 guest OS.

Workaround Restart the VM. Some of the areas that have seen work are the following:. The tcl package has been updated to version 8. As a replacement, the breezy package has been added. These two tools have been added in an effort to improve Rust developer tools. Python 3. Combined with the removal of Python 2 described in Section 5. Only Python 3 executable name python3 is now available. Python scripts usually expect the python executable without a version number to refer to the Python 2.

If the Python 3 interpreter is started instead, this can lead to applications failing or misbehaving. The squid package has been updated from version 4.

PHP version 8. There are many improvements in this version, some of which are:. The SUSE kernel module tools have been updated to better comply with the file system hierarchy standards and also clearly indicate that certain kernel modules will be disabled in a future SUSE Linux Enterprise release. The modprobe 8 tool now presents an interactive dialog in case the user attempts to load one of the obsolete kernel modules. The dialog offers to abort the load operation, load the kernel module once, or override the blacklisting status.

The zstd algorithm achieves much higher compression and decompression speed compared to xz , at the cost of somewhat lesser compression ratio. As a result, some reading operations during boot and installation are much faster. The module file extension has changed from. All SLE components that manipulate the kernel modules have been adapted. Third-party software that does in-depth examination of kernel modules may require adjustments.

The kernel cgroups API comes in two variants: v1 and v2. Additionally, there can be multiple cgroups hierarchies, exposing different APIs.

The main two that are relevant in this case are:. The kernel cgroups v2 is now supported in unified mode. However, the default is still hybrid mode. See the kernel documentation for more information about cgroups. The settings of kernel-preempt support timely reaction to external events and precise timing at the cost of overall system throughput. The specialized kernel-preempt package has been consequently removed from the distribution. For more information see the relevant kernel commit and the kernel documentation on boot interrupts.

However, the kernel did not support decompressing a zstd -compressed initramfs image before. The feature has now been enabled in the kernel but the default compression of dracut is still xz for now.

In addition to the firmware files being compressed, the packaging scheme has also been changed. Previously, all firmware files were shipped in the kernel-firmware package. Now, the files are split into sub-packages, and the kernel-firmware-all package will pull all the sub-packages into the system using the kernel-firmware provides symbol.

This is because it introduced a new kind of binary compatibility check, which is currently not compatible with the kernel in 15 SP4. It may also prevent loading modules in unexpected ways. This way there will be no BTF information on the modules but the Compile-Once-Run-Everywhere feature is still available to BPF programs that only trace kernel functions found within vmlinux. In previous SLES versions, the Btrfs file system implementation could not work with file systems formatted with a block size smaller than the configured kernel page size.

That means a file system formatted with 4-kilobyte block size could be mounted by the kernel using 4-kilobyte page size but not on another system that uses kilobyte pages. Starting with SLES 15 SP4, kernel with kilobyte page size can use Btrfs file systems formatted with the smaller block size smaller than the kernel page size.

The exisiting packages libbpf , bcc , and bpftrace have been updated and a new package cereal , the build-time dependency of bpftrace has been added. To reduce the attack surface, its usage has been restricted to privileged users only.

Privileged users include root. Value of 0 means “unprivileged enable”, and value of 2 means “only privileged users enabled”. However, you can explicitly request mmaps up to TiB. With QEMU 6. Sharing address spaces of processes with devices makes it possible to rely on core kernel memory management for DMA, removing some complexity from application and device drivers.

After binding to a device, applications can instruct it to perform DMA on buffers obtained with malloc. SVA mostly aims at simplifying DMA management but also improves security by isolating address spaces in devices. Outputting the driver version when using modinfo has been removed upstream. This has been done mainly because drivers developed as part of the Linux kernel tree are already versioned along with the kernel, and having a separate version was optional and confusing.

This meant that tools such as systemd generators could not know which LUKS device to activate to make a filesystem appear, unless all volumes were set up at boot.

The adcli command now supports the –dont-expire-password parameter. By default adcli will set this flag while joining the domain which corresponds to the default behavior of Windows clients. Unlike with the key option, the server and client do not need to share a key in a key file. This conflicted with the increasing demand for minimal product footprint, especially for products that were targeted for edge and embedded use cases.

This new version also obsoletes the previously separate plugins zypper-migration-plugin and zypper-search-packages-plugin , which have been removed. Abbreviated options not mentioned in –help are not supported. Previously, some abbreviated options worked due to the way Ruby parses options but they were not officially supported nor documented. On system start-up, the graphics console is first serviced by the framebuffer drivers.

In some scenarios, the handover can fail and the system graphics console can appear frozen. To use the new graphics driver, simpledrm , the module has to be loaded during boot. As root, on the console, type:. To avoid this, simply remove the file. This can be done from within the GRUB boot menu. There should be no difference from regular boot.

Everything should look as before. To verify that the simpledrm driver has been used, in the console type:. The former parameter enables simpledrm and the latter disables the native driver.

Afterwards, all the graphic output will be done by simpledrm. Finding the right console for the jeos-firstboot wizard can be tricky for the user and nothing was in place before to introduce the jeos-firstboot wizard to the user.

It adds a welcome screen to greet the user and tell them about which distribution is about to be started and configured. It shows the welcome screen on all the consoles. This solves the issue where the user might not know which console needs to be used for the jeos-firstboot wizard. It had previously been available only as a technical preview.

With Samba 4. We therefore deprecated SMB1 for a possible future update of Samba. This affects the Samba file server, its libraries and clients, as well as the kernel CIFS client cifs. This version of the protocol is insecure and usage of version 2. NIS netgroups support has been deprecated. It was removed upstream in Samba 4. NFSv4 with IPv6 is only supported for the client side. This artificial increase has been dropped in 15 SP4.

Networks and storage are now faster and having a large amount of reads in flight is usually not beneficial anymore. However, the reduced readahead size can result in worse performance in case of multiple parallel sequential IO streams on slow networks or with slow workloads. The TLS 1. TLS 1. We recommend no longer using TLS 1. However, not all packages, for example, Python, are TLS 1. The OpenSSL 3 library is currently not used by system applications but can be used by third-party libraries and applications already.

It can be used in processes together with the 1. It is frequently needed when doing work for the United States federal government. Since Linux kernel 5. However previously, the installer did not consider all the scenarios and thus might not have set the flag correctly.

NVMe-oF suffers from a well-known discovery problem that fundamentally limits the size of realistic deployments. Previously, file systems that supported fstrim were always trimmed if the device supported the TRIM command. In 15 SP4, the X-fstrim. While the file system will work and be supported until the date mentioned, it is best to re-create the file system:. SUSE Linux Enterprise was the first enterprise Linux distribution to support journaling file systems and logical volume managers in Later, we introduced XFS to Linux, which allows for reliable large-scale file systems, systems with heavy load, and multiple parallel reading and writing operations.

With SUSE Linux Enterprise 12, we started using the copy-on-write file system Btrfs as the default for the operating system, to support system snapshots and rollback. Instead of journaling changes before writing them in-place, it writes them to a new location and then links the new location in. Until the last write, the changes are not “committed”.

Because of the nature of the file system, quotas are implemented based on subvolumes qgroups. The numbers in the table above assume that the file systems are using a 4 KiB block size which is the most common standard. When using different block sizes, the results are different. By default, the file system drivers in SUSE Linux Enterprise Server 15 SP4 will refuse mounting file systems that use unsupported features in particular, in read-write mode.

However, note that setting this option will render your kernel and thus your system unsupported. Section 6. Find a summary of changes below. It also supports enrolling “recovery keys” and regular passphrases. A new credentials logic has been added to system services. This is a simple mechanism to pass privileged data to services in a safe and secure way. A concept of system extension images is introduced.

A new systemd-sysext tool can be used to merge, un-merge, list, and refresh system extension hierarchies. This allows debug logs to be enabled for select events, for example, just for a specific subsystem or even a single device.

A warning is emitted during build. Systems with the legacy cgroup v1 hierarchy are now marked as “tainted”, to make it clearer that using the legacy hierarchy is not recommended. PCI hotplug slot names on s systems are now parsed as hexadecimal numbers.

They were incorrectly parsed as decimal previously, or ignored if the name was not a valid decimal number.

PCI onboard indices up to are allowed. Previously, numbers above were rejected. This primarily impacts s systems, where values up to are used. Kernel API incompatibility: Linux 4.

The introduction of these new uevents which are typically generated for USB devices and devices needing a firmware upload before being functional resulted in a number of issues. To minimize issues resulting from this kernel change starting with systemd-udevd , the udev tags concept which is a concept for marking and filtering devices during enumeration and monitoring has been reworked: udev tags are now “sticky”, meaning that once a tag is assigned to a device it will not be removed from the device again until the device itself is removed that is, unplugged.

However, there are AutoYaST modules, which are only available in some products. Now there are different versions of the yast2-schema package, which only include the modules relevant for the particular product. YaST now makes it possible to select from several different visual themes. This includes a dark or a high-contrast mode, and several others. This is required, for example, for running rootless containers.

Previously, it was possible to set a group password in YaST. However, group passwords are an inherent security problem. Thus this features has been removed from both the user interface and AutoYaST.

Those elements are also ignored when importing a group from an existing AutoYaST profile. The installer proposes hibernation including adding the resume kernel option only if these conditions are met:. Support for System V init. To prepare for this change, use the automatically generated systemd service files directly instead of using System V init.

To then control the associated services, use systemctl. The automatic conversion provided by systemd specifically, systemd-sysv-generator is only meant to ensure backward compatibility with System V init. To take full advantage of systemd features, it can be beneficial to manually rewrite the service files. Use systemd service files instead. This command contacts the SCC and searches all modules for matching packages. This functionality makes it easier for administrators and system architects to find the software packages needed.

These release notes only document changes in virtualization support compared to the immediate previous service pack of SUSE Linux Enterprise Server. Support for native graphical installer has been added if virtio-gpu is used. The main use case is preventing access by third parties to data hosted in a public cloud. With this change, the upstream communities now define metadata that describe the firmware. This allows firmware to be automatically selected based on user-friendly configuration.

For example, the user can now simply specify EFI and the appropriate firmware will be selected. Xen has been updated to version 4. This change reduces the attack surface in the hypervisor. Note both projects have upstream Xen support merged now, so it is no longer recommended to use the Xen specific forks. QEMU has been updated to version 6. In previous versions, if no explicit image format was provided, some QEMU tools tried to guess the format of the image, and then process it accordingly.

Because this feature is a potential source of security issues, it has been deprecated and removed. It is now necessary to explicitly specify the image format. Enforcing good behavior and preventing both known and unknown security flaws from being exploited is highly recommended in the Linux world.

This allows a user to configure AppArmor policies at will right after the first boot of our Minimal-VM images. KubeVirt is a technology which enables container-native virtualization. It is now possible to prefer UEFI when creating new virtual machines. Some of the changes in this version are the following:.

Remove clashing -r command line shortcut for resize that clashed with existing reconnect shortcut. The respective packages are libpulp0 , the live patching core that must be pre-loaded into the application on start, and libpulp-tools containing the essential tools for building and deployment of patches.

Next, there are containers for the future live patches called glibc-livepatches and openssl-livepatches that will receive the fixes through future maintenance updates. However, new features and performance counters are not supported and the use of idle states might not be optimal. PowerVM LPAR guest secure boot with static keys with verification to extend the chain of trust from partition firmware to the OS kernel and includes key management.

KMIP provides a standard protocol for managing keys over the network to automate many key management tasks.

Once the VAS window is established, the userspace may use copy and paste instruction pairs to issue compression requests directly to NX coprocessor. For the logical partition migration, the hypervisor expects the partition to close all active windows on the sources system and reopen them after migration on the destination machine. That means the logical partition migration can not be used in 15 SP4 if NX is used by applications. The following command can be used to determine which process is currently using the NX coprocessor:.

Make sure no workload that uses hardware compression is running at the time of partition migration because it is possible that a workload might open VAS windows after the migration is initiated. Improve robustness of fadump further by isolating initrd to capture the vmcore inside the default initrd and activating it only during dump capture. Improved the numa locality of workload allocations. When Secure Boot is enabled for a logical partitioning LPAR , the Linux kernel enables lockdown which disables access to kernel memory from userspace.

It is expected that in the future a new interface to RTAS that does not require kernel memory access will be provided. Enhanced mechanism to handle the installer errors and summarize the errors in the installer a single popup message for everything and a page listing all the details.

On POWER9, transactional memory is partially emulated by the hypervisor, but this does not give the expected performance. Therefore, transactional memory is now disabled by default in the kernel. Introduces new tool zipl-editenv that allows a Linux on Z user to specify persistent configuration information that is evaluated during boot without the need to rewrite IPL records. Interface names could change between re-boots, invalidating any previously stored network card configuration To fix this, changes were made in the Linux kernel to indicate whether UIDs are unique to have systemd generate easy to predict interface names on preferably UID or FID.

Fixed performance problem for which the workaround was described in the Release Notes of earlier SLES 15 service packs. AP bus and zcrypt device driver uevent extensions that provide uevents for the following AP bus events: online state change, config state change, add crypto mode events. There were the following zkey -related changes stools : – extended LUKS2 functionality – integration of the zkey repository into an enterprise key mangement system with a KMIP interface.

Only register openssl-ibmca functions if libica signals the existence of a hardware function. Enhanced user information of the FCP device driver about HBA firmware version to improve handling of firmware update notifications. If this path is unavailable, re -IPL fails. This change implements a solution to keep the path to re-IPL up to date, and therefore work around transient path failures in many cases.

Install the latest qemu package from the update repository to fix this problem. Provides an indication in the guest that it is running securely. Cannot replace a real attestation and does not really provide additional security or could even create the false impression of security , but has been frequently requested by customers.

The tools in the virt-manager package, most prominently virt-install and virt-xml , are now aware of the IBM Z specific virtio types. Performance improvement through reading out complete counter sets with a single instruction and export them to user space without sampling involved. Driver enablement is done as far as available and requested. Refer to the following sections for any known limitations.

The intention of Uacce is to make sure the accelerator and process can share the same address space, so the accelerator ISA can directly address any data structure of the main CPU. This differs from the data sharing between CPU and IO device, which share data content rather than address. The feature is detected at runtime, and will remain disabled if the CPU does not implement the feature. Alternatively, contact your hardware vendor for whether a bootloader update is available that implements graphics output, allowing to instead use efifb framebuffer graphics in SUSE Linux Enterprise Server for Arm 15 SP4.

The bootloader of the system may need to detect the chip revision and to patch the Device Tree to pass the right compatible string to the kernel:. This will now result in failure to boot on rev. To check whether an LXA SoC-based machine will be affected by this, read the chip revision from its kernel:. If this prints 1. The raw application of the util-linux package has been removed.

The udev package has been removed as a dependency of the rpm package. The imgen package, containing Mellanox firmware generator, has been removed. For more information, see Section 5. For more information, see Section 9. Support for libvirt LXC containers has been removed. System containers using LXC have been removed. Use SSSD instead. The mkinitrd wrapper has been replaced with dracut everywhere and will be removed in the next major version of SUSE Linux Enterprise Server.

It is still available as an update-alternative for ftp , but it is no longed used by default. The default implementation of ftp is now the lftp executable. Use lftp directly instead. For more information, see Section 7.

The opa-fmgui package is not maintained upstream anymore. It has been deprecated, moved to the Legacy module, and will be removed in a future service pack.

The thunderbolt-user-space package does not work properly with a later revision of the TBT hardware. This includes packages implementing NIS, like ypserv.
