Functions

func IsVirtualCPU

func IsVirtualCPU() bool

IsVirtualCPU checks if the cpu is a virtual CPU running on ESX. It checks for the HV bit in the ECX register of the CPUID leaf 0x1. Intel and AMD CPUs reserve this bit to indicate if the CPU is running in a HV. See https://en.wikipedia.org/wiki/CPUID#EAX.3D1:_Processor_Info_and_Feature_Bits for details. If this bit is set, the reserved cpuid levels are used to pass information from the HV to the guest. In ESX, this is the repeating string "VMwareVMware".

func IsVirtualWorld

func IsVirtualWorld() (bool, error)

IsVirtualWorld returns true if running in a VM and the backdoor is available.
