I want to use both local (for better performance where it matters) and shared (for big slow disks) storage for a VM. Is it possible to live migrate such a VM?
If the storage was pure local, the migration command would be
virsh migrate vm qemu+ssh://new.hv.ip --copy-storage-all
This would copy the disk images prior to migrating the VM.
If the storage was pure shared, then the --copy-storage-all option is not needed.
So, what if one disk is local and another is shared? Won't copy-storage-all corrupt the disk on shared storage?
