And for those that don't, we should turn on X86_FEATURE_HYPERVISOR in the Linux enumeration code as we do for other features we detect independently.
Yeah, but all the hypervisors we detect right now are fine. Not surprising, since Microsoft won't certify Windows on your hypervisor unless you set the bit, and KVM/Xen/VMware are all certified (Hyper-V does not go through the same certification, but sets it anyway).
I got a second-hand report that VirtualBox doesn't set it---and I haven't verified that yet---but we don't even try to detect vbox right now.
