I'm now using Intel AMT and the wsmancli package to reboot/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?
