πŸ’– NAME πŸ’–

okay so bestie, welcome to fence_xenapi β€” the fence agent for Citrix XenServer, and it talks over XenAPI. this whole thing lives in the FENCE_AGENT(8) section of the System Manager's Manual, periodt. πŸŽ€


🌸 DESCRIPTION 🌸

fence_xenapi is a Power Fencing agent used on Citrix XenServer hosts. it uses the XenAPI β€” supplied by Citrix, no cap β€” to set up an XML-RPC session to a XenServer host. once that session is up and living its best life, more XML-RPC commands get sent over to switch on, switch off, restart, and query the status of virtual machines running on the host. slay. πŸ’…

the fence agent takes options on the command line and from stdin. Fenced sends parameters through stdin when it execs the agent. and you can absolutely run the agent by itself with command line options β€” super useful for testing and for turning outlets on or off from scripts. main character energy fr fr. ✨
