      Is that similar to slipstream?

      I tried to create a floppy like this

mkfs.vfat -C "virtio-floppy.img" 1440
sudo mount -o loop,uid=$UID -t vfat virtio-floppy.img /mnt
# copy drivers

      In that case can I convert

    <disk type='block' device='disk'>
      <driver name='qemu' type='raw'/>
      <source dev='/dev/vmhost_vg1/xp'/>
      <target dev='vda' bus='virtio'/>
    </disk>

to something like

    <disk type='block' device='disk'>
      <driver name='qemu' type='raw'/>
      <source dev='/dev/vmhost_vg1/xp'/>
      <target dev='hda' bus='ide'/>
    </disk>

and get away with it? If so, I must be missing something.
