ctoteam@buildingbuild:~$ sudo modprobe nbd
ctoteam@buildingbuild:~$

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.

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
