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/cor= e/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 ? Let me explain a little to make you better understand my reasoning behind t= his configuration. We work with segmented, separated networks. One network for public access, = one for storage traffic, one for management and so on. That means that if t= he nodes themselves have to do their own power-management, the nodes would = require three interfaces each, and the metal we are using for hosts just do= n=B4t have that. But if we can use the engine to do that, the hosts would o= nly require two interfaces, which most 1U servers are equipped with as stan= dard (plus one iLO/IPMI/whatev), so we can use them as hosts without issue.= Then the backend has one extra interface that it can use to communicate ov= er the power management network to the respective service processor with.
