No intranet. You can think of it as an isolated network between the = host and guest, and that's all. I just assigned an IP to ovs' LOCAL = interface on both hosts, and these ovs instances knew nothing about each = other, neither they forwarded packets between each other. I didn't want = to make things overcomplicated and decided not to mess with host's own = connection to the intranet, just something that sits on the other side = of vhost-user and replies to PINGs was perfectly OK for me. > I think this > does not matter if we are testing it functionally (whether live > migration could work), However I would still perfer to try ping > another host (say, host3) inside the intranet. What do you think? Yes, perhaps this would be better test, may be next time i'll do it. = Anyway, IIRC, PATCH v2 is coming.
