Hi,

engine executes power management (fencing) operation using different host in the same cluster/DC as target host reside. It's an oVirt requirement that each host in the same cluster and data center is able to connect to power management deviced of all other hosts in the same cluster/DC.
​

Here's simplified flow for defaults (fence proxy may be selected in the same cluster or DC)

1. Find all existing hosts in the same cluster​ which don't have connection issues (status Up, Maintenance, NonOperational for a reason different than network issues)

Ok


6. Select first host in Up (if no host is Up, then pick any other host, if no host found then fail and exit) and try to execute fence operation

Ok.
I presume that from the list of step 6 you exclude the hosts you got from step 1 that are a subset of it.
Otherwise you risk to try fence from an host that already failed three times to do so...
