I am trying to get my qemu vm to boot of 'VIRTIO_BLOCK', but am not very successful. I have got two setups:

A two day old qemu tree from git://git.savannah.nongnu.org/qemu
on a jetway board with a non kvm capable via c7 proc (30W),

and an older qemu-kvm (kvm-88-6-g2ebe329 (10.?)) on a AMD proc (130W)

The AMD boots guests with virtio_block, either with the -kernel switch or via the bios. The ViaC7 wil not. Nor the bios nor the kernel detect the vitio block device.

Somewhere on the internet I found this qemu-kvm option:

 -drive file=vmdisk1,if=virtio,boot=on

This boot=on, isn't in either of the man pages. qemu doesn't accept this option. qemu-kvm needs it to let the bios boot from the virtio_block device. I also noticed the qemu-kvm bios has a boot menu which can be accessed by F12. qemu has not.

boot=on is in qemu-kvm.git but not in qemu.git yet.
