[Openstack-operators] qemu 1.x to 2.0

Oops - I just noticed the initial libvirt packages I pasted were wrong...
too early in the morning, I guess.

I started out with:

libvirt0 1.2.2-0ubuntu13.1.2~cloud0
libvirt-bin 1.2.2-0ubuntu13.1.2~cloud0
python-libvirt 1.2.2-0ubuntu1~cloud0

And then moved to:

libvirt-bin 1.2.2-0ubuntu13.1.6~cloud2
libvirt0 1.2.2-0ubuntu13.1.6~cloud2
python-libvirt 1.2.2-0ubuntu2~cloud0
