Hmm, perhaps a bug somewhere else is overwriting the cpufeatures bit for X86_FEATURE_VMX. Let me see if I can reproduce from net-next.
If you have any further suggestions for debugging, I'm happy to help try to figure this out. To my eyes, it looks like somehow bits get reset... It's definitely not clear to me how this happens.
There is the get_cpu_caps call.. but that seems to correctly call apply_forced_caps at the end.
That's all I have time for today.
Thanks, Jake
