v0.25.0

Changelog v0.25.0

Know before update

• In version v0.25.0, support for the module's operation with CRI Containerd V2 has been added.
  After upgrading CRI from Containerd v1 to Containerd v2, it is necessary to recreate the images that were created using virtualization module version v0.24.0 and earlier.

Features

• [core] In version v0.25.0, support for the module's operation with CRI Containerd V2 has been added. #1395
  In version v0.25.0, support for the module's operation with CRI Containerd V2 has been added.
  After upgrading CRI from Containerd v1 to Containerd v2, it is necessary to recreate the images that were created using virtualization module version v0.24.0 and earlier.
• [observability] New Prometheus metrics have been added to track the phase of resources such as VirtualMachineSnapshot, VirtualDiskSnapshot, VirtualImage, and ClusterVirtualImage. #1356
• [vm] MAC address management for additional network interfaces has been added using the VirtualMachineMACAddress and VirtualMachineMACAddressLease resources. #1350
• [vm] Added the ability to attach additional network interfaces to a virtual machine for networks provided by the SDN module. For this, the SDN module must be enabled in the cluster. #1253
• [vmclass] An annotation has been added to set the default VirtualMachineClass.
  To designate a VirtualMachineClass as the default, you need to add the annotation
  virtualmachineclass.virtualization.deckhouse.io/is-default-class=true to it.
  This allows creating VMs with an empty spec.virtualMachineClassName field, which will be automatically filled with the default class. #1305

Fixes

• [module] Added validation to ensure that virtual machine subnets do not overlap with system subnets (podSubnetCIDR and serviceSubnetCIDR). #1324
• [vi] To create a virtual image on a PersistentVolumeClaim, the storage must support the RWX and Block modes; otherwise, a warning will be displayed. #1289
• [vm] Fixed an issue where changing the operating system type caused the machine to enter a reboot loop. #1358
• [vm] Fixed an issue where a virtual machine would hang in the Starting phase when project quotas were insufficient. A quota shortage message will now be displayed in the virtual machine's status. To allow the machine to continue starting, the project quotas need to be increased. #1314

For more information, see the changelog and minor version release changes.

Changelog v0.24.0

Features

• [api] Remove setting of VolumeSnapshotClass. Set field deprecated in CRDS's. #1274

• [vd] Fail with error on insufficient PVC size #1295
• [vd] Set ImageNotReady/ClusterImageNotReady condition when VI/CVI is missing. #1286

v0.23.1

Changelog v0.23.1

Fixes

• [api] A virtual machine with the AlwaysOn run policy can be restored with the forced mode. #1294

For more information, see the changelog and minor version release changes.

v0.23.0

Changelog v0.23.0

Features

• [core] All containers have been switched to read-only mode, which is part of efforts to enhance security and ensure integrity control of the virtualization components. #1244

• [vmrestore] Added the ability to forcefully restore a virtual machine from a snapshot using the restoreMode parameter. This parameter has two possible values:

  • Safe - a safe recovery option when there are no conflicts with the virtual machine's resources;
  • Forced - a forced recovery option that can be applied to a running virtual machine but may lead to destructive consequences if conflicts arise during the recovery process.

  If the forcibly restored virtual disks are used by another virtual machine or the restored IP address is reserved by another virtual machine, the recovery process will fail, and this will be reported in the VirtualMachineRestore resource status. #1115

Fixes

• [core] Fixed the placement of the virtualization management component on system nodes when they are present in the cluster. If there are no system nodes in the cluster, it will be placed on master nodes. #1260
• [vd] For a virtual disk in Filesystem mode, fixed the ability to dynamically attach (hotplug) to a virtual machine. #1241
• [vd] Fixed the creation of virtual disks using NFS storage with the no_root_squash option. #1210

For more information, see the changelog and minor version release changes.

v0.22.0

Changelog v0.22.0

Features

• [api] The storage classes managed by the local-path-provisioner module are now deprecated for VirtualImage and VirtualDisk creation. #1243

Fixes

• [api] The allowed name lengths for resources have been adjusted and the corresponding validation has been added:
  • ClusterVirtualImage: 48 characters (instead of 36)
  • VirtualImage: 49 characters (instead of 37) #1229
• [module] Now in clusters with High Availability mode, the virtualization components on the master nodes use 3 replicas. #1208
• [module] Fixed the deployment of the virtualization module in HTTP mode (when using Disabled or OnlyInURI options for the https.mode setting), which could lead to blocking the execution of the deckhouse queue. #1207
• [module] Fixed the deployment of the module on nodes with CentOS, Rocky Linux, and Alma Linux with SELinux enabled (Enforced). Now the installation completes without errors. #1203
• [module] Reduced the module size to 50MB (previously 445MB). #1181
• [vm] Removed unnecessary warnings about virtual machines running in privileged mode — such messages are no longer displayed, as this is standard and expected behavior of the system. #1202
• [vmsnapshot] Fixed the hotplugging of existing images when restoring a virtual machine from a snapshot. #1198
