I'm running Devstack to try and create a OpenStack installation for testing. I'm running within a VM, my localrc is below.

During the install, the command openstack --os-cloud devstack-admin --os-region RegionOne network create --project 7cd79cb2cf15462eb20c9f918a25271e private errors with die_if_not_set 211 NET_ID 'Failure creating NET_ID for private 7cd79cb2cf15462eb20c9f918a25271e'

There doesn't seem to be much on Google about this. Any help would be most welcome.
