kvm: vmx: Raise #UD on unsupported RDRAND A guest may not be configured to support RDRAND, even when the host does. If the guest does not support RDRAND, intercept the instruction and synthesize #UD. Also clear the "allowed-1" bit for RDRAND exiting in the IA32_VMX_PROCBASED_CTLS2 MSR. Signed-off-by: Jim Mattson <jmattson@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
