Hi,
It looks like the 4.14 linux kernel has something which breaks
postcopy; 4.13 and 4.15 both seem OK, but both Peter and myself ran
into problems with double faults after postcopy migration on a Fedora
27 host, and I've recreated the same problem on upstream kernels
from v4.14.0 through v4.14.0.
The stand alone userfaultfd tests seem ok though.
I might try some further bisecting, but for now I think I'll just
flip to a bleeding edge 4.15.
Dave
