My big wish is that they don't try to merge the KVM tool into the
kernel code. It's a separate userspace project, and there's no reason
for it to be bundled with kernel code. It just makes the kernel
sources larger. The mere fact that qemu-kvm exists means that the KVM
interface has to remain backward compatible; it *is* an ABI.

So integrating kvm-tool into the kernel isn't going to work as a free
pass to make non-backwards compatible changes to the KVM user/kernel
interface. Given that, why bloat the kernel source tree size?

Please, keep the kvm-tool sources as a separate git tree.
