Should SeaBIOS automatically pick > up virtio devices and attempt to boot them? Yes, it can handle virtio-blk (and soon virtio-scsi too). You probably want to implement the fw_cfg (firmware config) interface which is used as communication path between qemu and seabios, to pass around stuff like e820 table and option roms. Also http://sgabios.googlecode.com/svn/trunk is nice when working with a serial console. HTH, Gerd
