44 | 43 | Known Issues |
45 | 44 | ------------ |
46 | 45 |
|
47 | | -• Usage data for Instance Backups does not update after the final backup of an Instance is deleted |
| 46 | +• Starting 4.21 VM snapshots are supported for instances on KVM hosts. However, volume snapshots and VM snapshots cannot coexist. |
| 47 | + Restoring a volume snapshot will remove any existing VM snapshots and may lead to data loss. |
| 48 | + There is a UI issue where error messages in such scenarios may not clearly indicate the problem. |
| 49 | + |
| 50 | +• When managing and unmanaging UEFI-based VMs on KVM hosts, migration of such VMs may fail in certain scenarios. |
| 51 | + This typically occurs when a VM that was unmanaged and later re-imported is started on a different host and then |
| 52 | + migrated back to its original host. The migration fails because the VM domain still exists on the original host, |
| 53 | + resulting in a conflict. As a workaround, manually remove the old domain from the original host before attempting the migration again. |
