You can create a dummy cpu in halted state, have a look at
http://kraxel.fedorapeople.org/patches/0004-xen-groundwork-for-xen-support.patch
;)

While I'm at it:  There is a patch queue with at
http://kraxel.fedorapeople.org/patches/

The plan is to submit that stuff upstream, so regular qemu will have xen
support.  Right now the patch queue has only paravirt bits.  It comes
with a new machine type and a bunch of backend drivers (console,
framebuffer, disk, nic).  Will be posted to the list when it is ready
for submission (framebuffer still has some problems).

cheers,
  Gerd
