Applied the first three qemu-server patches already, thanks!

For the nested-flag I'm not fully sure yet if this is enough also for Windows
guests to run e.g. WSL with a non-host CPU type like x86-64-v3, which I might
not put into scope originally, but for many users it will IMO be assumed as
"has to work" if we put this in the changelog.
