As somebody has already said it would have to be a really old kernel to not handle virtio-block, and it's more likely that your bootloader and/or initrd are confused by sda becoming vda. However if your kernel supports it then virtio-scsi should be even better than virtio-block and shouldn't cause the device name to change. Tom
