I think to be acceptable to qemu (and probably also for Xen) the devices would have to be written in C. C++ is more pain that it's worth in this context. Of course there's no reason why we couldn't use the subset of C that's also valid C++. You could also write C++ wrappers round the interface for bochs to use. I'm not a fan of binary plugins (for the same reasons I'm don't like binary kernel modules), and don't think there's any real need to them. I can't see any good reasons why open source devices would need to be broken out into a separate shared library. If you do want to accommodate proprietary binary plugins then C++ is a really bad idea. The C++/libstdc++ ABI simply isn't stable enough to make this a realistic option.
