SUSE Virtualization v1.7.1 Release Notes

The Virtual Machine Auto Balance add-on allows SUSE Virtualization to leverage the Kubernetes Descheduler for rebalancing of virtual machine workloads. When enabled on a multi-node cluster, the add-on deploys the Descheduler and a related configuration. The Descheduler evicts pods that are not optimally placed according to administrator-defined policies, enhancing resource utilization and improving cluster performance.

SUSE Virtualization automatically detects GPUs that support Multi-Instance GPU (MIG)-based partitioning. In v1.7, virtual machines can share vGPU devices backed by NVIDIA GPUs with this capability (such as the A100, H100, and H200). To leverage this feature, you must define the MIG profiles for your GPU, enable the MIG configuration, and enable the vGPU device associated with the MIG configuration.

Starting with v1.7, SUSE Virtualization supports external storage devices that use multipath I/O (MPIO) to provide redundant data paths while preventing device identification conflicts. Through the os.externalStorageConfig setting, you can define the precise configuration (including device blacklisting and whitelisting) that the multipath daemon uses to manage devices and ensure storage stability.

SUSE Virtualization v1.7 allows you to add and remove network interface controllers (NICs) from running live-migratable virtual machines without downtime. When you hotplug a NIC, SUSE Virtualization migrates the virtual machine and connects the specified interface through bridge binding. Virtual machines that were created using the Harvester Node Driver and the Harvester Terraform Provider do not support this feature.

In SUSE Virtualization v1.7, you can use the VM Import Controller add-on to import virtual machines using Open Virtual Appliance (OVA) files, which are a single-file version of OVF packages. SUSE Virtualization supports downloading these OVA files via both HTTP and HTTPS. For endpoints that use HTTPS, you can configure a secret that includes basic authentication credentials for the URL and a CA certificate.

SUSE Virtualization v1.7 introduces a new option to the upgrade-config setting that enables pausing of automatic node upgrades for all or specific cluster nodes. This capability is essential for scenarios requiring manual maintenance or verification on the nodes before the upgrade continues. Once these tasks are completed, you must then explicitly instruct SUSE Virtualization to resume the upgrade process on the target nodes.

Hugepages allow the Linux kernel to allocate memory in chunks larger than the default size. In SUSE Virtualization v1.7, you can configure transparent hugepage settings for each node to increase the overall system performance. Additionally, you can monitor memory allocation for both anonymous (transparent) and persistent (static) hugepages on the SUSE Virtualization UI.

SUSE Virtualization v1.7 allows you to create VLAN trunk networks with multiple, overlapping VLAN ID ranges. When a virtual machine is attached to a VLAN trunk network, the guest operating system and applications are allowed to send and receive packets tagged with any of the VLAN IDs within the specified range.

v0.1.25 of the Harvester CSI Driver supports volume snapshots, providing point-in-time snapshots and restoration for guest cluster workloads. You can create, list, and delete snapshots of persistent volumes, and create new volumes from existing snapshots. To use this feature, you must ensure that the CSI snapshot controller and the required manifests are deployed on the guest cluster.

Harvester CSI Driver v0.1.25 is used in the following SUSE® Rancher Prime: RKE2 versions:
