Hi folks,
I'm trying to to attach a disk to an instance using libvirt. The problem
is, this disk has external snapshots. The process tried was:
1 - Attach a disk in the domain:
* virsh# attach-device instance-00000006 /tmp/disk.xml[1] --live*
2 - Snapshot the disk[2]:
* virsh# snapshot-create instance-00000006 --quiesce --xmlfile
/tmp/snap-from-disk.xml[2] --disk-only*
3 - Dump the domain XML and create a new disk file from it:
*virsh# dumpxml instance-00000006*
* ... [3]*
4 - Dettach the device and re-add it using the new disk file:
* virsh# detach-device instance-00000006 /tmp/disk-with-snap.xml[4]*
* Device detached successfully*
* virsh# attach-device instance-00000006 /tmp/disk-with-snap.xml *
* error: Failed to attach device from /tmp/disk-with-snap.xml*
* error: internal error: unable to execute QEMU command
'device_add': Property 'virtio-blk-device.drive' can't find value
'drive-virtio-disk1'*
Question, is this operation supported? If yes, how is the correct procedure?
