Frankly, I do not see much similarity here.

When I ping from NetVM (or from FirewallVM as well) I can see replies from
Internet fine. In fact I am using NetVM on my workhorse laptop for quite a

In my case, there is no issue with pci passthru - just the link
between the net frontend and backend does not cope well with forwarded packets.
