Yeah, prefer v2 as well.  Sorry if that means wasted time on your
part.

Though I'm also thinking I prefer to have pc-1.0-precise defined in
both precise's qemu-kvm 1.0, and later qemu 2.x, and requiring some
purely-on-precise action to switch the machine type from pc-1.0 to
pc-1.0-precise before migrating to trusty/later.

But as I mentioned elsewhere there's still the concerns of (a) how
much other still (like virito-net) will still break, and (b) the
practical issues of how to ship the old roms.
