+
+command:
+qemu-system-x86_64 -m 1024 -enable-kvm /root/centos6.img -enable-kvm -device pci-ohci,num-ports=100,masterbus=1

+The ohci doesn't check the 'num-ports' property and would case an out-of-bands write,crash the qemu process.
+
+    ohci->num_ports = num_ports;
+    if (masterbus) {
+        USBPort *ports[OHCI_MAX_PORTS];
+        for(i = 0; i < num_ports; i++) {
+            ports[i] = &ohci->rhport[i].port;
+        }
+
+The version of qemu is 2.6.0 release from
