Ok, seems like getting further.
I made sure that I added
--libvirt_type=xen
Along with
--libvirt_uri=xen:///
Now I get:

libvir: Xen error
Even though I have
--glance_api_servers=A.B.C.D:9292 set (not on the same machine)
It seems like the local nova node didn't get that? (Even though its printout of the gflags settings show it did).

Looks like there is something wrong with the xml. You might try navigating to the instances dir/instance-00000001/libvirt.xml and see if there is anything that looks wrong.
if you try: virsh create dir/instance-00000001/libvirt.xml you might get some more useful error message about what is wrong with the xml
(or LIBVIRT_DEBUG=1 virsh create...)

Any idea about that one? Is this another setting for libvirt+xen usage that needs to be disabled?

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.

Hi all,
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).
