Notable changes

  • [PR #16512][awels] Decentralized Live Migration now has a separate condition in VMI and VMIM to indicate any issues
  • [PR #16489][lyarwood] Add new PrefixTargetName VolumeRestorePolicy for VirtualMachineRestore that creates restored volume names using the format {targetVMName}-{volumeName}. This provides predictable, readable names while avoiding collisions when restoring snapshots to different target VMs.
  • [PR #16404][iholder101] Add missing "Direct" and "Extended" options to Hyperv TLBFlush
  • [PR #16491][lyarwood] virt-operator now configures client rate limiting (default: 200 QPS / 400 burst) to improve reconciliation performance when processing large numbers of objects. Rate limits can be customized via --client-qps and --client-burst flags or VIRT_OPERATOR_CLIENT_QPS and VIRT_OPERATOR_CLIENT_BURST environment variables.
  • [PR #16600][woojoong88] Fix block volume hotplug breaking autoattachVSOCK
