There still seems to be an issue with this series.  When running:

sudo qemu-system-x86_64 -hda ./10gig.img -snapshot -cdrom 
isos/ubuntu-7.10-server-amd64.iso -boot dc

Occassionally, I'll get:

kvm_run: failed entry, reason 5
kvm_run returned -8

There's nothing in dmesg though.  Can you reproduce this?  If not, I'll 
dig in some more.
