Starting with Windows Server 2012 and Windows 8, if CPUID.40000005.EAX contains a value of -1, Windows assumes specific limit to the number of VPs. In this case, Windows Server 2012 guest VMs may use more than 64 VPs, up to the maximum supported number of processors applicable to the specific Windows version being used. https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/tlfs For compatibility, Let's introduce a new property for X86CPU, named "x-hv-max-vps" as Eduardo's suggestion, and set it to 0x40 before machine 2.10. (The "x-" prefix indicates that the property is not supposed to be a stable user interface.)
