I patched my host (kernel 4.14.12) , and I also have Windows 10 which self-updated to https://support.microsoft.com/en-gb/help/4056892/ . While I can see that the PTI has been activated in the host: % dmesg | grep isolation [ 0.000000] Kernel/User page tables isolation: enabled ... but I am not so sure about the guest systems. Anyway, with the patch active in the host the guest machines are just fine for gaming.
