Greetings everyone, I am having another problem that I was hoping to get some assistance with.   I have created my own custom fence agent for some tasmota-flashed wifi smart plugs, that can control plug power input to ovirt nodes. This works great; however I am running into a problem getting it added to ovirt as a power manager. I got the custom fence agent added with engine-config -s, and it shows up in the webui to select as a power management agent, then I put in the details for the plug, IP address, login, password, and press the "test" button, which passes, and shows the status as power=on.  Once I save the settings, however, it is logged in the engine.log file that fencing will fail, because there is no node available to proxy the operation.  When I go back into the power management settings, and press "test" again, then I get the error: "Test failed: Failed to run fence status-check on host 'ovirt1'. No other host was available to serve as proxy for the operation." I have the agent script in /usr/sbin/ on all nodes, execute permissions set, and I can run it manually at the command line just fine, so I am really at a loss here as what to check.  What am I missing here? Please help. Thank you for your time.  Script: #!/usr/libexec/platform-python -tt from urllib.parse import quote import requests import sys import atexit sys.path.append("/usr/share/fence") from fencing import * def set_power_status(conn, options):         if "on" in options["--action"]:             response = requests.get(buildUrl(options, "on"))         elif "off" in options["--action"]:             response = requests.get(buildUrl(options, "off"))         return def get_power_status(conn, options):         response = requests.get(buildUrl(options, "status"))         if "\"Power\":0" in response.text:             return "off"         elif "\"Power\":1" in response.text:             return "on" def buildUrl(options, action):         cmnd = {             'on' : 'Power On',             'off' : 'Power Off',             'status' : 'Status'         }         return "http://" + options["--ip"] + "/cm?user=" + quote(options["--username"]) + "&password=" + quote(options["--password"]) + "&cmnd=" + quote(cmnd.get(action, "Error")) def main():         device_opt = ["ipaddr", "login", "passwd", "web"]         atexit.register(atexit_handler)         all_opt["power_wait"]["default"] = 5         options = check_input(device_opt, process_input(device_opt))         docs = {}         docs["shortdesc"] = "Fence agent for Tasmota-flashed Smarthome Plugs"         docs["longdesc"] = ""         docs["vendorurl"] = ""         show_docs(options, docs)         ##         ## Fence operations         ####         result = fence_action(None, options, set_power_status, get_power_status)         sys.exit(result) if __name__ == "__main__":         main()
