Comment 6 for bug 1680050

Hi Apolihron,
thank you for your report and you help to make Ubuntu better.

I see you are running virt-manager which calls into ther libvirt python bindings and then fails.

To understand what versions you really have around I'd ask you to report:
$ dpkg -S /usr/bin/kvm-spice
$ dpkd -S /usr/share/virt-manager/virtManager/asyncjob.py
$ dpkg -S /usr/lib/python2.7/dist-packages/libvirt.py
$ dpkg -l python-libvirt qemu-kvm virt-manager

The apparmor profile is generated when starting a guest and set in place for it.
But I wonder if that might just be something like an guest xml from another system and not all the required files around. The checks above will help.

Could you share the guest xml of the guest that is causing this?
If you don't have it you can get it with
$ virsh dumpxml <guestname>

Also where is the "Unable to complete install" coming from?
what is the actual command you were running so that one can try to reproduce?
