This time, when I tried to build kvm modules > on ubuntu 16.04 (4.4.0-45-generic) with kvm-kmod, I got the following error: The public kvm-kmod repository is way out of date. I have a local copy that should more or less work, but it would probably require a few tweaks for particular kernel versions. I'll push the current status of my tree in the next few days (at most on Monday). Any further fixes are welcome, you can also use GitHub pull requests for that.
