It's very difficult to do this unless the hardware provides a "processor
serial number" instruction that isn't privileged, i.e., doesn't cause
an interrupt that the KVM system can intercept and simulate the output

Otherwise, even if you can discover some sort of identifier that can be
extracted from the KVM environment, someone else can "improve" KVM to
provide a simulation that be configured to a fixed value.
