Hi,

i try to test live-migration using this command:

#virsh migrate --copy-storage-all --verbose --live kvm1776
qemu+ssh://nodeb/system


Instant error message:

error: internal error: unable to execute QEMU command 'blockdev-mirror':
Cannot find device=drive-sata0-0-0 nor node_name=drive-sata0-0-0

If i use scsi or virtio its complaining with the corresponding names.
Example: drive-virtio-disk0

Its backed via zfs.
