I'm now using Intel AMT and the wsmancli package to reboot/power off/power on my entry level systems... but now I want oVirt to use this for fencing.
I created 3 xml files: powercycle.xml (uses PowerState 10), poweron.xml (uses PowerState 2) and poweroff.xml (uses PowerState 8). Here is the poweroff.xml file: <p:RequestPowerStateChange_INPUT xmlns:p="http://schemas.dmtf. org/wbem/wscim/1/cim-schema/2/CIM_PowerManagementService"> <p:PowerState>8</p:PowerState> <p:ManagedElement xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/ addressing" xmlns:wsman="http://schemas.dmtf.org/wbem/wsman/1/wsman.xsd"> <wsa:Address>http://schemas.xmlsoap.org/ws/2004/08/ addressing/role/anonymous</wsa:Address> <wsa:ReferenceParameters> <wsman:ResourceURI>http://schemas.dmtf.org/wbem/wscim/1/ cim-schema/2/CIM_ComputerSystem</wsman:ResourceURI> <wsman:SelectorSet> <wsman:Selector Name="CreationClassName">CIM_ ComputerSystem</wsman:Selector> <wsman:Selector Name="Name">ManagedSystem</wsman:Selector> </wsman:SelectorSet> </wsa:ReferenceParameters> </p:ManagedElement> </p:RequestPowerStateChange_INPUT>
I can then reboot or power on/off the server with: wsman invoke -a RequestPowerStateChange http://schemas.dmtf.org/wbem/ wscim/1/cim-schema/2/CIM_PowerManagementService -h [AMT IP] -P 16992 -u admin -p [amt password] -J /fencing/poweron.xml (or poweroff.xml, etc).
My question is, how do I move from this to using this for fencing in oVirt?
At the moment oVirt doesn't officially support AMT as fence agent. But I've just looked that on CentOS 7 we already have fence-agents-amt-ws package, so please try to install fence-agents-amt-ws package and test if it's working for your server. If above agent is working fine, then please take a look Custom Fencing oVirt feature [1], which should allow you to use fence_agent_amt_ws agent in oVirt. Am I right Eli?
