v1.2.0

Changelog v1.2.0

Features

• [core] Added the VirtualMachineSnapshotOperation resource for creating a virtual machine based on a VirtualMachineSnapshot. #1727
• [module] Added the ability to clean up DVCR from non-existent project and cluster images:
  • By default, this feature is disabled.
  • To enable cleanup, set a schedule in the module settings: .spec.settings.dvcr.gc.schedule. #1688
• [module] Added validation for the virtualization ModuleConfig that prevents decreasing the DVCR storage size and changing its StorageClass. #1628
• [module] Improved audit events by using more informative messages that include virtual machine names and user information. #1611
• [observability] Added new metrics for disks:
  • d8_virtualization_virtualdisk_capacity_bytes: Metric showing the disk size.
  • d8_virtualization_virtualdisk_info: Metric with information about the disk configuration.
  • d8_virtualization_virtualdisk_status_inuse: Metric showing the current use of the disk by a virtual machine or for creating other block devices. #1592
• [vmbda] Added detailed error output in the Attached condition of the VirtualMachineBlockDeviceAttachment resource when a block device is unavailable on the virtual machine node. #1561
• [vmclass] For the VirtualMachineClass resource, version v1alpha2 is deprecated. Use version v1alpha3 instead:
  • In version v1alpha3, the .spec.sizingPolicies.coreFraction field is now a string with a percentage (for example, "50%"), similar to the field in a virtual machine. #1601
• [vmrestore] The VirtualMachineRestore resource is deprecated. Use the following resources instead:
  • VirtualMachineOperation with type Clone: For cloning an existing virtual machine.
  • VirtualMachineOperation with type Restore: For restoring an existing virtual machine to a state from a snapshot.
  • VirtualMachineSnapshotOperation: For creating a new virtual machine based on a snapshot. #1631

• [vdsnapshot] Fixed an error that could lead to inconsistencies between VirtualMachineSnapshot and VirtualDiskSnapshot resources when creating a snapshot of a virtual machine with multiple disks. #1668

Chore

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
