We can, however, extract the part providing 'hyperv=on' option to x86 machine types which is valuable on its own. Picking up four other patches from the original RFC to minimize the code churn in future (x86_cpu_realizefn()). Changes since RFCv3: - Rename 'hyperv_features' to 'default_hyperv_features' in X86MachineClass [Eduardo] - Move x86_cpu_hyperv_realize() invocation after x86_cpu_expand_features()/ x86_cpu_filter_features() as we need to reference cpu_has_vmx().
