Public bug reported:

I'm following the Installation guide on a CentOS 7 box.

When i try to launch an instance with nova using:

nova boot --flavor m1.tiny --image cirros --nic net-id=2a3bd890-1afd-
4d22-9cfb-e9e9415f1a03 --security-group default --key-name oliva public-
instance

I get the following error:

ERROR (ClientException): Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible.
<class 'keystoneclient.exceptions.BadRequest'> (HTTP 500) (Request-ID: req-fa00f28f-ab95-441d-91cb-68f9353ae16f)

Output of nova flavor-list, nova image-list, nova secgroup-list, neutron
net-list follows:
