We have been trying to deploy nova (Bexar) for the past week on a single machine. We can install and configure nova on a fresh Ubuntu 10.10 server and even successfully start VMs but we have not been able to connect to those VMs. Neither ping nor ssh work (yes, we have done the euca-authorize steps).

We've tried all of the steps from the ( . We've tried asking other questions, ( and ( (no replies). We've tried going on IRC, giving bits and pieces of information about our problems and getting good troubleshooting tips in return but, ultimately, nothing that has worked for us. We've read about a similar problems: ( was already solved and the patch merged in Bexar and ( doesn't seem to be relevant anymore (can't find --flat_interface reference in any of the nova- --help).

So, out of desperation, here is all of the information about our configuration (IP addresses changed) in the hopes that someone can pinpoint what the problem is.

Is our networking configured properly for Nova? Why can't we ping or ssh to our instances?

Any answers or network troubleshooting tips are greatly appreciated!

** Installation Architecture ** By design our network architecture very closely resembles the Nova example installation architecture. (

Keep in mind that, at the moment, we are only trying to install to a single machine.
