Command: sudo nova-rootwrap /etc/nova/rootwrap.conf blkid -o value -s TYPE /dev/nbd12 fails

When setting up a simple openstack deployment ( two nodes without block/object storage ) and attempting to start an instance the following error can occur:

Instance failed to spawn

This is because blkid is filtered by rootwrap.
