That makes sense... I wasn't creating that file. D'oh! Working for me now too.

The tests are all using fully emulated Ethernet... the issue is that
the ping test ensures that on timeout an error is returned. Even
though it is an emulated MAC, the timeout in the network stack is
still there.
I'll work on a patch that adds a way to change the ping timeout to
make this faster.
