KVM supports embedded PowerPC (440 and e500 at the moment), and

systems).
If you're interested, you should check out the trees at
http://powerkvm.org .
Wow, didn't know about that port. I'll have a look.
The main port was PowerPC 440, and that and e500 support are already
upstream in KVM. Some details are available here:
http://www.linux-kvm.org/page/PowerPC
The 970/Cell stuff Alex is doing is only loosely connected to that
(ppc64 supervisor mode is very different from 440/e500), and that's
the
first URL I gave you.
Actually "my 970 stuff" virtualizes ppc32 on ppc64, so we don't have
to mess with conflicting kernel address rooms.
The architecture as is however should allow you to easily add ppc32
host support as well as ppc64 guest support, as long as you prevent
the memory segments to collide (BAT for ppc32, 0xc/0xd SLB entries for
ppc64).
So I for my part would welcome any help I can get to have KVM run
smoothly on non-embedded POWER :-).
