Apparently it had nothing to do with the failed commit. After restarting the guest, I could do the snapshot and the active block commit. But... I can't do it two times after each other without restarting the guest...
Any clues? Van: Dominique Ramaekers Verzonden: donderdag 21 januari 2016 8:20 Aan: libvirt-users@redhat.com Onderwerp: Error after failed external snapshot. Hi, I use this procedure to backup my VM's: http://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit It works on my current host: Compiled against library: libvirt 1.2.16 Using library: libvirt 1.2.16 Gebruikte API: QEMU 1.2.16 Draaiende hypervisor: QEMU 2.1.0 Now I'm doing a test on a testing host: Compiled against library: libvirt 1.2.21 Using library: libvirt 1.2.21 Gebruikte API: QEMU 1.2.21 Draaiende hypervisor: QEMU 2.5.0 The first time, the active block commit failed because the block action was stuck on 100% and I got this error: 'block copy still active: disk 'vda' not ready for pivot yet' I did a 'virsh blockjob PCVIRT1 vda -abort' and started 'virsh blockcommit PCVIRT1 vda --active --verbose -pivot' again. This way, the external snapshot was commited ok. Now I get this error when I want to create an external snapshot: fout: internal error: kan QEMU commando 'transaction' niet uitvoeren: The feature 'snapshot' is not enabled I can't find a lot of information about this. Some help will be appreciated. Greetings, Dominique.
