Subject: [PATCH] Enable nova-libvirt to be updated

Libvirt shuts down existing virtual machines.  To solve this problem,
the /var/lib/libvirt directory needs to be persisted.  By persisting
this directory in the nova data container, libvirt can communicate
with the sockets setup by the previous data container.
