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

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.

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

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.
