I see two possible sources to the problem: XENBUS: Device with no driver ... and setuproot: moving /dev failed: No such file or directory ... switchroot: mount failed: No such file or directory
Is there libvirt xml equivalent to the XEN configuration file's root = "/dev/xvda1 ro"?
OK, yeah. The XENBUS: Device with no driver can be ignored, I'm

The problem is probably what you think, that you don't have a root=/dev/xvda1 line in there. Other people will have to comment on whether there is a libvirt XML equivalent, since I'm just not sure.

I think the target dev here can just be appended with an one?
Stefan I used virsh xmldump to create an xml file. I comment out the bootloader element since XEN create fails with an error when the bootloader element is empty. Also I commented out the target dev vif directive because it is ignored by create. The domain id directive is also ignored. This is a commented copy of the working xml:
