DESCRIPTION

fence_cxs is an I/O Fencing agent used on Citrix XenServer hosts. It uses the XenAPI, supplied by Citrix, to establish an XML-RPC sesssion to a XenServer host. Once the session is established, further XML-RPC commands are issued in order to switch on, switch off, restart and query the status of virtual machines running on the host.

fence_xenapi accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_xenapi can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
