[BUG] kvm-84 segfault

[Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com>]

Distro:
        - Ubuntu 8.04

CPU:
        - Intel(R) Core(TM)2 Duo CPU     T7700  @ 2.40GHz

qemu-system-x86_64:
        - QEMU PC emulator version 0.9.1 (kvm-84), (I Built locally)

Bug:

I had installed distro kvm (for Ubuntu 8.04) and created a guest Fedora10
image. I eventually uninstalled the distro kvm and built kvm-84 myself.
I have been using this kvm-84 and the Fedora10.img for a while with
libvirt (0.6.0) which again, I built locally.

Today when I try to create a new Fedora10 guest image:

        $ qemu-img create -f qcow2 Fedora10.img 10G

        $ sudo qemu-system-x86_64 -hda Fedora10.img -m 1024 -boot d \
                -cdrom Fedora-10-i386-DVD.iso
        Segmentation fault

/var/log/messages shows:

        kernel: [  193.077299] qemu-system-x86[7810]: segfault at 000001a0
                eip b7cd72f5 esp bfd5e0cc error 4

If I remove the 'sudo' it gives "Permission denied" on /dev/kvm, but the
same command works fine (in slow motion).

Pls let me know if I can collect other debug info.
