[Testbed-admins] Node mapping

[Chris Benninger <cbenning@cs.uvic.ca>]

Hi again,

So I am trying to create a simple dumbbell experiment as an example. I have 14 nodes "free" and 2 of them are reserved for the testbed project.

The experiment swap-in log give me a "No possible mapping" message and fails. Also each node is in the "Boot wait mode", I assume that is where they need to be? Any Ideas? Thanks!

Here is the swap-in log:
