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.
