[John Garbutt <John.Garbutt@xxxxxxxxxx>]

There are a few bugs with Raw images Mate is working though at the moment (see folsom release notes too):
https://bugs.launchpad.net/nova/+bug/1055413
https://bugs.launchpad.net/nova/+bug/1055431

Maybe you are hitting those bugs?
How new is the version of nova you are running?
Can you give us the glance cli output for your image showing all the metadata (or the horizon view)?

Thanks,
John

Subject: [Openstack] fails to launch instance

Hi all,

I am running openstack on Ubuntu 12.04 (with XCP).
I create an ubuntu image (Raw). The creation of the image is successful. However, when I try to launch an instance using this image, I get this error:
