In a replicated ZFS environment, containers can be easily migrated from one node to another, as the only supported migration mode of a running container is restart mode. It works quick and reliably if replication happends e.g. hourly or more often.
For VMs, the system does not allow to select restart mode and suggest online migration - which will fail if ZFS replication is enabled for the VMs file systems. So one has to stop the VM, the do an offline migration and restart it manually on the new node.
It would help if PVE detects the VMs replication (it knows!) and suggest restart mode as only possible migration mode and performs it according to the way it works for containers.
