The explicit ordering part seems clunky to me.  How about:

-drive name=vda,if=virtio -drive.vda.file filename.img

What's nice about this syntax is it generalizes well.  You could have:

-drive.vda.if virtio -drive.vda.file filename.img
-net nic,model=rtl8139,name=foo -net.foo.macaddr 00:11:43:55:44:22
