Detecting Nested HypervisorsCheat developers sometimes use nested hypervisors to create a transparent analysis environment: they run the game in a VM, with the cheat running in the VM’s host. Detection of nested hypervisors relies on timing anomalies: CPUID executed inside a nested VM is handled by two hypervisors in sequence, introducing double the overhead. RDMSR and WRMSR instructions similarly have amplified latency. Statistical analysis of hundreds of timing measurements can reliably distinguish native execution, single-level virtualization, and nested virtualization.
