Hi
* Trying to get drive-backup command, getting permission denied. :(
sudo virsh qemu-monitor-command --hmp my-instance --cmd
drive_backup drive-virtio-disk0 /tmp/foo.vda.img
Looks like apparmor issue. What can I modify to make this work ?
* Couple of other questions
drive-backup :
* The doc seems to claim that it gives a point in time copy
of the drive. So I assume that no need to take any snapshot etc.. and
merge back in.
* does it internally use snapshot ? Does this hook in to
doing fsfreeze and unfreeze using guest agent and does it automagically
? I do not see any options here.
* Suppose I have base <-- sn1 --<-- sn2 (QEMU active) . does
it take data from sn2 only ? or base+sn1+sn2 .. full drive and creates
a new qcow2 sparse file.
Thanks
/Jd
