Thanks for testing! I didn't even thing about seabios as a testing target.

I tried to do what you described, and built seabios with:

$ cat .config | grep 'KVMTOOL\|DEBUG'
CONFIG_KVMTOOL=y
CONFIG_DEBUG_LEVEL=9

But when booting, it just hangs on:

$ ./lkvm run --firmware ~/seabios/out/bios.bin -d dummy
  # lkvm run -k /boot/vmlinuz-4.2.0-17-generic -m 448 -c 4 --name guest-12566


And same result with --virtio-legacy...

What did I miss?


Thanks,
Sasha
