[libvirt-users] Block Commit: [100 %]error: failed to pivot job for disk vda

[Thomas Stein]

Hello.

I'm seeing this error while doing a backup of a VM.

+ virsh blockcommit kaltura vda --active --verbose --pivot
Block Commit: [100 %]error: failed to pivot job for disk vda
error: internal error: unable to execute QEMU command
'block-job-complete': The active block job for device
'drive-virtio-disk0' cannot be completed

I'm on qemu 2.2.0 and libvirt-1.2.11.

Does someone else see this error? Libvirt.log says:

2015-01-07 11:18:07.000+0000: 19355: warning :

Any ideas?

thanks and cheers
