[Qemu-devel] SMP

I realize that this may be pushing the future a bit, I just wanted to
start the discussion.

What challenges do we (or does Fabrice) face
- creating an qemu SMP guest?
- multithreading qemu to utilize a SMP host?
- integrating with something like mosix so you could build a virtual 50
CPU box in a lab across 50 real machines (or a 250 CPU box on 50
machines to avoid waiting on IO)
- how would numa figure into this (I'm completely ignorant of what a
numa machine looks like)

I am very interested in single image clusters (as a spectator), but what
I've seen so far is coupling machines at a level that seems to high and
complex to me.  It seems silly that each machine has to have a full OS
installed and configured just right.  Building a big single image
machine on linked VMs would allow us to run qemu on a stripped down OS
(just drivers and basic services) or a heterogeneous network (even a mix
of linux kernels would beat mosix).

Thanks for any consideration.
