libvirt users - May 2016 - Ubuntu 14.04 virsh 1.2.2 blockcommit hangs at 100% / command 'blockcommit' doesn't support option --pivot

Hello All,

I think I have seen this in previous bugs. Trying to live backup qcow2
images. I am able to virsh snapshot-create-as and virsh domblklist shows
correct new source, but I am unable to commit back changes to qcow base. I
get the above error.

Libvirt at 1.2.2-0ubuntu13.1.17
Qemu is (2.0.0+dfsg-2ubuntu1.22)

I tried compiling latest libvirt, but cannot get it to connect to socket on
installed binaries

Anyone get this working on Ubuntu 14.04?

Dear Liam,

You need to upgrade to the latest LTS version of Ubuntu (16.04).

I refer to my message to this mailing list on 17/03/2016:
Hi everybody,

Following this user mailing list over a period of time, I saw a few messages
regarding not being able using the external snapshot feature.

I refer to this procedure:
http://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit

I would like to mention this hoping it will help those users:
Using external snapshots works perfect again in qemu 2.5.0 together with this
patch https://bugzilla.redhat.com/show_bug.cgi?id=1300209

Full version list on which I did my testing:
Compiled against library: libvirt 1.3.1
Using library: libvirt 1.3.1
Gebruikte API: QEMU 1.3.1
Draaiende hypervisor: QEMU 2.5.0

Greetings,

Dominique.
