Well, saving & restoring domain is like migration. Therefore, guest ABI
must be preserved. Therefore it's not possible to hotplug or hotunlpug
devices as it would change the guest ABI. What you can do though, is to
change the backends (e.g. disk location to your domain has changed, so
you should be able to change the disk <source/>).
