This is just the EAX value.
This is based on:
Microsoft Hypervisor CPUID Leaves:
http://msdn.microsoft.com/en-us/library/windows/hardware/ff542428%28v=vs.85%29.aspx
Linux kernel change starts with:
http://fixunix.com/kernel/538707-use-cpuid-communicate-hypervisor.html
VMware documention on CPUIDs (Mechanisms to determine if software is
running in a VMware virtual machine):
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1009458
QEMU has the value HYPERV_CPUID_MIN defined.
