Depends how much verification you want, how you're booting, and if you want it automated. I have tested booting manually via qemu by booting qemu with the raw disks. Be careful though, you don't want to boot all the way unless you make sure the disks can't be written to by qemu (use dm-snapshot or losetup -r). Of course, this isn't the same as booting with your BIOS on your hardware, but I've found in practice its sufficient for my needs. Glenn
