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. - Ted
