[VIDEO] Eucalyptus: set up your environment

Hi,
in order to help my students to start-up with Eucalyptus, I have realized
this small video with the three preliminary steps: download credentials, set file/dir permissions and generation of key pair.

Here my first attempt:

I know that there is much to improve (english, remove hesitations, create on live a key and not just show how to), but right now I would like to know what is your opinion about that.

Thanks,
Massimo
