I'm playing around with KVM on an ebony board (440GP), just trying to
get it to work, really. I followed the instructions at
http://www.linux-kvm.org/page/PowerPC and I used the 2.6.33 branch of
the kvm kernel repository. When I try to run kvm, qemu appears to
abort and actually logs me off.
Doing a little debugging, I found that qemu_memalign() is calling
abort because posix_memalign() is failing. I haven't done any more
debugging than that.
Well, I discovered that the default memory is 128M, and that's too much
memory for a VM running on a machine with 128M. I fixed that problem,
and now it's doing something, though no console so not sure what.
I guess my questions below and the patch still apply.

Since I already had to fix a kernel issue to get it the kernel code to
initialize since the platform was reported as ppc440gp, not ppc440,
I'm wondering how hard it's going to be to get this working. Does
anyone have this working at all? Should I back up to a previous
version? Any help would be appreciated.
Thanks,

Here's the change I made to get kvm in the kernel to initialize:
