I've run into that before too..

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.
Eventually the guest gets a local network that won't conflict with the user's
network infrastructure.
Obviously, if you have a 10.0.x.x, a 172.16.x.x and a 192.168.x.x network,
having a configurable guest network is probably loads simpler.
