The problem with just setting kvm_version to a huge number is that if you built a kvm development snapshot a long time in the past, and you run it now, then you will be turning on features your old development snapshot didn't necessarily have. On the other hand, if you are running development snapshots, you get to keep both pieces when things break. Maybe we can set the kvm_version number very high like you say, but also dump a warning message out to the logfile saying this is a development version so the poor sap who has to debug something like this has a fighting chance.
