KubeVirt
v1.8.1Orchestration & ManagementKubeVirt v1.8.1 is a small patch release fixing two specific bugs: virt-handler domain-notify server crashes and VMExport failures with long PVC names.
breakingUpgrade if virt-handler crashes are disrupting VM lifecycle events
The domain-notify server handles communication between virt-handler and running VMs. If it exits unexpectedly without restarting, VMs can become unresponsive to lifecycle operations (start, stop, migrate) without obvious errors. If you've seen unexplained VM management failures after a virt-handler pod restart, this is your fix. Patch as soon as possible on v1.8.0 clusters.
enhancementVMExport now works reliably with long PVC names — review your naming conventions
If you use VMExport for backup or migration workflows and your PVCs follow long naming patterns (common with dynamic provisioners or namespace-prefixed names), test VMExport after upgrading. The prior failure was silent enough to cause confusion — confirm your export pipelines are functional post-upgrade.
