Yup, and kvm-unit-test will always need to exist for that.

But we need something that makes it easy to test ARM, PPC, s390, etc so that 
when we do things like the memory API, it's possible for a developer to do 
reasonable testing without having to track down 100 different images and tool 
chains.
