Thank you for using Ubuntu and reporting a bug. libvirt sometimes doesn't give very helpful error messages, so I am going to ask you to run a series of commands to help locate the problem.

Can you give the output of the following:
$ cat tserver.xml | /usr/lib/libvirt/virt-aa-helper -r --uuid libvirt-c04cd76d-029b-7644-13ab-c2d144543ea2 --dryrun -p 0

and:
$ cat tserver.xml | /usr/lib/libvirt/virt-aa-helper -r --uuid libvirt-c04cd76d-029b-7644-13ab-c2d144543ea2 --dryrun -p 1

If the second works, as a workaround you can adjust /etc/libvirt/qemu.conf to have:
allow_disk_format_probing = 1

and then restart libvirt with:
$ sudo /etc/init.d/libvirt stop
$ sudo /etc/init.d/libvirt start
