Adam,
Ah, yes. I've found that link and have been trying to follow it. The IXL statistics, when enabled, cause a crash in a constructor somewhere. But so does simply adding an interface. My process doesn't even get to the first printf in the program on the very first line. I've sent an email earlier with the binary and the objdump output. Why are things dying in the constructors?

Hi Richard,
looks like I overlooked this mail. In case it helps, there is https://l4re.org/use-cases/net-swt-curl/

Hi there!
I've gotten two linux vms to come up and automatically set their IPv4 address and login for me. (l4vio_net_p2p) They can ping each other just fine. Now I would like to get them to talk to my l4Re-native server. I see an lwip library, and I see that it has a virtio backend that appears to connect lwip to the virtual network. What I can't seem to find is an example that uses it?
I have one vm at 192.168.1.2, and the one at 192.168.1.3. I would like to assign my lwip virtio-net interface to 192.168.1.100, and of course have them all talk TCP and UDP to each other. I can handle lwip and sockets, I just have no clue how to get it configured and initialized under l4re. Any examples and/or helpful hints? .cfg files? modules.list? Code? Github link?
Thank you for your time!
Richard
