Our users will hate us if we do this. We should look at XP's actual market share, not formal statements from Microsoft. If market share starts dropping, we can scale back support in qemu. Providing less than optimal performance is a lot better than starting up with no networking. In any case optimal performance requires a non-default selection (virtio). -- error compiling committee.c: too many arguments to function
