[PATCH 0/2] KVM: nVMX: expose VMX capabilities as MSR features

[Paolo Bonzini]

These patches add the VMX capability MSRs to the /dev/kvm ioctls
KVM_GET_MSR_FEATURE_INDEX_LIST and KVM_GET_MSRS, so that userspace
can easily probe which VMX features are actually supported by KVM.

This will help the implementation of nested hypervisor migration,
even for heterogeneous clusters.

Patch 1 is just refactoring, while patch 2 implements the feature.

Thanks,

Paolo
