I think you said dom0 too many times there. Was one of them supposed to
be a domU?

You need xen enabled in both dom0 and domU. In fact the easiest thing to
do is to use the same kernel for both.

The error messages suggest to me that you are missing some key piece of
generic infrastructure, like perhaps /dev/pts.

I'd strongly recommend you find a way to run udev on this platform so
that it can sort out the content of /dev for you (this was the cause of
all the missing device nodes which you tripped over earlier too).
