Known Issues
Starting 4.21 VM snapshots are supported for instances on KVM hosts. However, volume snapshots and VM snapshots cannot coexist. Restoring a volume snapshot will remove any existing VM snapshots and may lead to data loss. There is a UI issue where error messages in such scenarios may not clearly indicate the problem.
When managing and unmanaging UEFI-based VMs on KVM hosts, migration of such VMs may fail in certain scenarios. This typically occurs when a VM that was unmanaged and later re-imported is started on a different host and then migrated back to its original host. The migration fails because the VM domain still exists on the original host, resulting in a conflict. As a workaround, manually remove the old domain from the original host before attempting the migration again.
