All the virtual machines have interfaces within "xen-bridge", together with eth0. The only exception is the one with ID 13, which is "testMachine", according to your "xm list" output. Instead, it's interfaces is within "tmpbridge", alone, unable to communicate anywhere.

Take look on it's config file. I bet it has not defined a "bridge" variable within "vif" directive. Compare the config with a working one.
