 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.

 Yes, perhaps this would be better test, may be next time i'll do it. =
Anyway, IIRC, PATCH v2 is coming.
