This is a bit tricky: when the engine brings up the host it also creates
the management bridge and this could lead to a temporary network down on
the selected interface for the bridge creation time (a couple of seconds?)
I tried it on a LAN and ansible ssh connection always survived but I 'm not
sure it's always true.
