Bug in reboot when using scsi or virtio

Guest boots and runs fine, but does not see boot device on guest reboot
if if=scsi or if=virtio is used.

Boot Screen after reboot:
Booting from Hard Disk...
Boot from Hard Disk failed: could not read boot disk
... More failed boot devices that shouldn't boot anyway...
FATAL: No bootable device

CPU: Intel(R) Pentium(R) D CPU 3.00GHz
KVM: kvm-74
Host: Debian Lenny - Vanilla 2.6.26.2
Guest: Debian Lenny - Vanilla 2.6.26.2
Command: {
export QEMU_AUDIO_DRV=oss
qemu-system-x86_64 \
        -m 1024 \
        -std-vga \
        -soundhw es1370 \
        -name 'Debian Vitrual Host' \
        -net nic,macaddr=52:54:00:12:31:02 \
        -drive file=/projects/stu/kvm-drives/debian.img,if=scsi,boot=on \
        -net tap,ifname=tap2 -daemonize
}

Still exists with -no-kvm-* combinations.
Software not built to run without kvm

To reproduce, just bring the guest host up with either a if=scsi or
if=virtio.

Can you try using the extboot.bin from the last version that worked  
for you?

Hey Brian,

The last version I had been running is kvm-70. After copying the
extboot.bin from that version over to the share/kvm directory, the
system rebooted several times in scsi and virtio mode.

Please let me know if you would like me to build any additional versions
 for testing.

This was caused by the extboot rom writing into itself, thus failing 
checksum on the next reboot.  I fixed this for kvm-75 by reloading the 
rom on reset.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.

Thanks Avi,

Should I test against the daily to verify?

I've reproduced it locally and verified the fix, but of course 
additional confirmation is welcome.
