I have a suspicion that all of these should really be per-vnet for correct semantics with VIMAGE, with the IS_DEFAULT_VNET check earlier dropped completely. I haven't read around the rest all that much, but this would at least seem to prevent port re-use by a different vnet, which is perhaps "good enough" but I think this is something that should be fixed in the mid-term.
