Description of problem:

When Launching a new Instance I'm getting the following error:

RDO nova should come configured with lock_path=/var/lib/nova/tmp
in /etc/nova/nova.conf

/var/lock is controlled by the system, rather than nova,
and so the nova process doesn't have write access there.
Is there some reason why /var/lib/nova/tmp doesn't suffice?

Note it's important to define some value for lock_path,
as leaving it as "None" will trigger buggy tmp dir logic in nova.
