inside Xen-DomU VM (4 CPU + 4 GB RAM), Today I have installed Ubuntu 12.04 LTS + devstack.

I can access OpenStack horizon GUI, created one VM instance (cirros-0.3.1), but it gives me error after created VM.

ideas?

More info:

I have only a single public IP address, so I will have to use NAT port mapping or something. It is possible, that I have overlooked a network (or other) configuration step. How to figure out what's missing? The UI error is pretty useless. In UI, I also see:

"Unable to get log for instance "cab91c65-9fe4-4f96-b317-575f190fb7b0"."
