‚ÄčAt 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‚Äč.

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?
