So I tried a few things, namely switching Virtualbox network modes. But I could not see packets between the VMs.
I imagine when traffic is between VMs #Virtualbox is not putting the packets in the TCP/IP stack where #Wireshark on the host can see them. Only when the traffic crosses to the host or the network beyond does Wireshark (or #tshark) see it.
I don't want to capture traffic on the VMs themselves (having to install Wireshark or something else on Windows 98...).
So I searched around and found the article below in the Virtualbox wiki on network tracing.
You can essentially configure the NIC on each VM to capture all packets and log them to a pcap. So this is what I'll use.
