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… *Van:* libvirt-users-bounces(a)redhat.com [mailto: libvirt-users-bounces(a)redhat.com] *Namens *Ishmael Tsoaela *Verzonden:* maandag 27 juni 2016 11:56 *Aan:* libvirt-users(a)redhat.com *Onderwerp:* [libvirt-users] block commit failed at 100% 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
