Open Stack

Hi Dan,

I tried it on Ubuntu 12.04. However VM could not obtain an IP address from
a DHCP server.
Any advice?
If more information is needed, please let me know.

Note: checking out 'FETCH_HEAD'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b new_branch_name
