Also known as Paravirtualization level or maximim cpuid function present in
this leaf.
This is just the EAX value for 0x40000000.
QEMU knows this is KVM_CPUID_SIGNATURE (0x40000000).
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
Also:
http://lkml.indiana.edu/hypermail/linux/kernel/1205.0/00100.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.
