[rhos-list] Problem launching a VM.

Anybody have a clue what this is all about? I launch a VM, it gets an IP, spins at 'spawning' for a while, goes back to 'networking', then fails with this error in the "compute.log".  It looks like something with the console.  I'm running Folsom with Quantum Networking. One compute/controller node and one networking node.
