1.3GB is more than enough. When you get that message, usually space
has already dried up, or there is a problem authenticating with
xenapi.

Check that:

xenapi_connection_url
xenapi_connection_password

are set correctly, and that you can reach dom0 from your devstack instance.

Have a look at your localrc, xenrc, and nova.conf, see if you can find
anything wrong with them.

Hope this help!
