[one-users] ubuntu-image from marketplace doesn't get an IP

Tue Jan 29 06:25:55 PST 2013

I've just tested the ubuntu image and gets the IP selected by
OpenNebula. It also configures the root authorized_keys wth
SSH_PUBLIC_KEY parameter in context. Can you send us the template used
to create the VM?
