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. Regards, Anthony Liguori Since your tests also link against the host environment, it potentially makes tests much simplier to write (as you aren't reinventing an OS). I think this makes this style of test more appropriate for something like QEMU.
