Also allow to enable/disable the hypervisor cpuid bit in the guest config file. We need to disable the hypervisor cpuid bit to get Hyper-V going.The change itself looks plausible to me. However I don't know much about cpuid; can you get an ack from a hypervisor maintainer or an suitable expert ?Keir? Tim?I think the hypervisor bit should be given a better name than 'raz' -- although it is read-as-zero on real hardware that doesn't distinguish it from other raz bits, or describe what it does. 'hypervisor' maybe, to match 'X86_FEATURE_HYPERVISOR' elsewhere in the Xen code? With that change, Acked-by: Tim Deegan<tim@xxxxxxx> New version with that change attached.
