When switching from IDE to virtio, you need to first build a new initrd
in the guest with e.g.:
$> mkinitrd --with virtio_pci --with virtio_blk -f /boot/initrd-$(kernelversion) $(kernelversion)
You only need to do this once. After that, if a new kernel is installed
while you're booted off a virtio disk, then mkinitrd will include the
modules automatically.
You will also need to specify /dev/vdX on the kernel root= line and make sure your init script inside your initrd triggers the virtio drivers at boot so that the /dev/vdX are created.
