The KVM mailing list would probably be the best place
(kvm@vger.kernel.org), as we just backport existing upstream patches to
the stable kernels.

That being said, jumping from 4.4 to 4.14 is a very large leap (2 years
of development), it might be good if you can try something in the
middle?

Or, an earlier 4.14.y?  Try 4.14.3 or so and if that works, then it is
easier to use 'git bisect' to track down the offending patch.
