I just downloaded your two files and did the kvm command that you provided and I
did not get the segfault, rather it booted up to this:
/proc/cmdline: No such file or directory
Debian GNU/Linux wheezy/sid (none) tty1
(none) login:
but otherwise, I do not get the segfault that you experience. The only
difference here is that I was running in Squeeze. Unfortunately, I could not
find a wheezy box with amd64 and kvm extensions. I'll ask around to see what I
can find.
