+          With <code>&lt;hint-dedicated state='on'/&gt;</code> and
+          <code>&lt;cpu mode='host-passthrough'/&gt;</code>, it
+          allows a guest to enable optimizations when running on dedicated
+          vCPUs. QEMU newer than 2.12.1 and kernel newer than 4.17
+          are required.
