Ownership has changed. Check these two directories:
/var/lib/nova/instances /var/log/nova
You can fix this by changing ownership to nova.nova. e.g.: # chown nova.nova /var/log/nova/nova-manage.log
In my case I've noticed that nova-manage.log had 0 bytes and root owned it. My locks dir was also belonging to root as well.
