Thanks,

I'll give it a try and see if the libvirt stuff works, or I'll just switch to the native xen usage in openstack.

NBD shouldn't be needed for xen.  You probably need to set
--nouse_cow_images
which will stop nova from trying to use qcow2 as the image format.

Is there supposed to be devices there??

You probably should try to do "modprobe nbd" before running nova. This will create list of nbd devices that nova uses to inject keys and get images ready to start VM from them.

Kind regards, Yuriy.

Another error that others may have seen:
Is it supposed to continue even if this fails?
This is for running xen btw (this is running on nova-compute in a xen dom0 instance).
