You can abort the commit with ‘virsh blockjob vm /mnt/… --abort’ and retry the 
commit again. In my experience the second time, the blockjob always completes 
successfully.

I’ve changed completely from using file images to logical volumes. I get the 
feeling, using external snapshots with file images isn’t really stable on the 
commit part. I never can reproduce a stuck commit, so I haven’t filed a bug 
rapport for this behavior…

Hi All,

I am new to libvirt and would appreciated some assistance with libvirt backups.

I am backing up some VM and coming accross and issue where "Block commit" does 
not completely finish, causing libvirt to write to snapshot:


root@xxx:~# virsh blockjob vm /mnt/diskimage-backups/vm.snap-201606210230.qcow2 
 --info
Active Block Commit: [100 %]

The state does not change, is the anyway around this ?

libvirtd (libvirt) 1.3.4
QEMU emulator version 2.3.0
