I don't think we can pull in: - extboot - ia64 - in-kernel pit[1] - associated command line options - device passthrough The question is, if we dropped those things, would people actually use qemu.git instead of qemu-kvm.git. If the answer is "no", what set of things do we need in order for people to focus on qemu.git instead of qemu-kvm.git. [1] I'd like to revisit this discussion. We originally went the in-kernel pit route because of difficulties changing qemu. That's a bad reason to put something in the kernel. I'd prefer to see us fix qemu. After that, we can look at in-kernel pit and see if there are any remaining advantages (like performance). If it's significant, we can still merge in-kernel pit. Regards, Anthony Liguori
