The point I was trying to make is that qemu could easily arbitrate the guest network based on how the host is configured. If the host has a 10.0.x.x network (and I suppose if we want to be thorough, a 10.0.x.x route), then it punts to 172.16.x.x (and does the same check) and then tries a couple of 192.168.x.x networks.

I really dislike this kind of guesswork. It makes it very hard to debug/reproduce problems, and means you're never really sure what qemu is going to do. IMHO One of the really nice features of qemu is that it is host independent.

I agree with this - guesswork and invisible options can be confusing. That's why I suggest what I think is the simplest solution: Just let this be overridable on the command line.
