     A specific error message is returned if there is a timeout error.
 
+Reboot
+-------
 
+The Reboot is used to reboot a VM.
+
+ 
+There are two types supported: HARD and SOFT. A SOFT reboot attempts a graceful shutdown and restart of the server. A HARD reboot attempts a forced shutdown and restart of the server. The HARD reboot corresponds to the power cycles of the server.
+
+**NOTE:** The command implementation is based on OpenStack functionality.  For further details, see http://developer.openstack.org/api-ref/compute/.
