You're right. In that case, I agree, moving the code into nova-compute should be fine.

I'm expecting precisely one compute node per XS host.  Are we talking at cross-purposes?  As far as I'm concerned, nova-compute runs on every XS host (and the same would be true if we were using KVM, as far as I can tell).
