The algorithm of selection a host to act as a proxy for PM commands is
quite naive: any host from the system with status UP.

You can see how it is being selected in FencingExecutor.FindVdsToFence()
from
ovirt-engine/backend/manager/modules/bll/src/main/java/org/ovirt/engine/core/bll/FencingExecutor.java

There is no other algorithm for the selection at the moment.

How would you handle a case in which hostA isn't responsive ? Wouldn't
you prefer trying to perform the fencing using other available host ?
