I got a machine up and running 13.04. I followed the instruction and set up MAAS. Current state I need nodes to be in "ready" state, so that I can install juju with MAAS. However, the nodes are stuck in "commissioning" state. I checked the clocks in each node, and they all synchronize well.
I also tried "$ maas-cli maas nodes accept-all" for Automatic Discovery I am not sure how to fix this.
