I booted linux and got the following:

I tried to boot the rumprun iso with a static IP address (which is a
little odd on GCE since I had to guess the IP address the instance
would be assigned). It booted and produced no errors. Running the
following netcat hung for a long time before I eventually killed it
and produced nothing in the serial console:
echo "test" | nc 10.240.0.2 5001
With the linux instance, it fails immediately with:
(UNKNOWN) [10.240.0.2] 5001 (?) : Connection refused
or if I run my code on the linux instance:
echo "test" | nc 10.240.0.2 5001
I got your message
The code I am running on the server is here:
https://gist.github.com/christopherhesse/c8dc88783af0e69ce5d3
So I guess DHCP would be a nice thing to try, except that it doesn't
seem to work for me.
Has a rumprun iso with networking been run successfully on GCE and/or EC2?
