Right, so you have free space here to provide the motivation for the
backport.  It's a large change and it isn't immediately obvious that it's
stable branch material.


This does not introduce any new features.
Users expects the guest not to have any cpuid features that the host
cannot honnor. There has been multiple bug reports regarding this in
the past of Fedora users. I imagine other users have seen it too.

If it hits users then it's obviously important. Note though that Mark found some bugs there, so we need to either backport Mark's patches or look for a simpler workaround.
