Ok, you are running qemu emulating a Realtek NIC.

This is where the RTL chip is found by L4IO.

This is where ORe tries to initialize the Intel e1000 driver (for a NIC
which is not there).

This results in loopback being the only device found and driven by ORe...

The ORe version in the disk image is configured to include a RTL8139+
driver. It may be that this is not the default when compiling ORe. Go to
l4/pkg/ore/server and run "make config" - there you can select which
drivers to include. This should get you up and running.
