In Red Hat Enterprise Virtualization (RHEV) 3.5, newly-added hosts to a cluster in 3.5 compatibility mode will use json-rpc by default. This can be overriden and xml-rpc used instead, which was previously the only option.
Existing hosts will still use xml-rpc, but can be modified to use json-rpc. This requires that the host be placed into maintenance mode first.
