You should simply start booting a UP guest on an SMP host, see where

For the time being, I've yet to see UP guest crashing on SMP host. On
the model, that is...
Last time I tried to run a guest in a 2 core model, it hanged and
crashed after a while. Anyway, I will investigate. So I gather critical
sections have been dealt with and it's just a matter of ironing bugs
right now?
Depends when you tested. V4 was definitely unusable on SMP.
With my patches merged in Christoffer's v5 release, the basics should be
covered (correct SMP setup in the boot-wrapper and KVM, MPIDR
virtualization).
If you find any problem (and let's face it, I'm sure you will... ;-),
I'll be happy to investigate.
I had the guest boot process crash on a page fault on the v5 series.
Consistently. I just didn't have time to investigate yet.
I was also running v5, however I didn't record the exact crash behavior,
since I assumed I was having the same results as everyone. I will look
into it now.
