Open Stack

i have downloaded image from
http://cloud-images.ubuntu.com/releases/11.04/release/ubuntu-11.04-server-uec-amd64.tar.gz

and also facing the same problem, cannot access or my running instances.

However, I am facing another weird problem here. I can easily launch an
instance from the dashboard, but when I try to run it from command line, I
lost my internet connection, and this happens to all of my PCs connected to
the same router. To solve this I have to restart the network of the
controller node to get connected again.
