NAME
       fence_xenapi - Fence agent for Citrix XenServer over XenAPI

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 session to
       a XenServer host. Once the session is established, further XML-RPC com-
       mands 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.

       Vendor URL: http://www.xenproject.org
