The RDPRU instruction gives the guest read access to the IA32_APERF MSR and the IA32_MPERF MSR. According to volume 3 of the APM, "When virtualization is enabled, this instruction can be intercepted by the Hypervisor. The intercept bit is at VMCB byte offset 10h, bit 14." Since we don't enumerate the instruction in KVM_SUPPORTED_CPUID, intercept it and synthesize #UD.
