The KVM mailing list would probably be the best place (kvm@xxxxxxxxxxxxxxx), 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. thanks, greg k-h
