Bug Description

I am using Debian Wheezy with xcp. I am upload image.raw into glance:
#glance add name=xen.raw disk_format=raw container_format=ovf < xen.raw
Then try to boot:
# nova boot --flavor 1 --image e132ec71-f42a-4854-a3f4-16ae3a8b1ce9 --key_name mykey --security_group default xen.raw

Can you launch a VM without using nova?
This looks like the xcp-xapi package is not working on your system.

Thank you for help. I have updates about this bug.
The reason of "nova.rpc.amqp Failure: ['INTERNAL_ERROR', 'device model failed to initialise: qemu-dm exit" is qemu could not work properly with bridge mode of xcp.
You must write "openvswitch" in /etc/xcp/network.conf and then configure xcp for working with this mode (from manual "/usr/share/doc/xcp-xapi/README.Debian.gz").
Then you virtual machine run almost properly. But I have new problem.
#nova boot --flavor 1 --image e132ec71-f42a-4854-a3f4-16ae3a8b1ce9 --key_name mykey --security_group default xen.raw
Wait for a wile and watch console of VM:
#xtightvncviewer 127.0.0.1:5901
My VM is freeze and nothing helps (reboot too).
I can not understand, why VM running under qemu? This is pvm machine... May be I send wrong parameters from nova to xcp?

Closing this bug, maybe file a new one about the new issue you encounter. Looks like you have usage issues rather than a bug to report, though, in which case I'd recommend posting a message on the users general mailing-list instead.
