Thanks! Just to make sure (and to conclude our discussion with Roman):
with your Qemu maintainer hat on, do you agree with the design decision
that KVM_GET_SUPPORTED_HV_CPUID's output value changes when
KVM_CAP_HYPERV_ENLIGHTENED_VMCS gets enabled? This differs from
KVM_GET_SUPPORTED_CPUID (where we always list all feature bits even if
they require explicit enablement)?
