Ugh this was a few months ago and I haven't done much with nova recently. IIRC, all you have to do is connect to the :1 vnc on the nova host. So if you have VNC and a GUI on your nova host, you can do that from the host with your favorite vncviewer (ubuntu comes with remote desktop viewer) and connect to :1. So the string you would type into the remote desktop viewer program would be<div>
<br></div><div>localhost:1</div><div><br></div><div>You can do this through ssh port forwarding as well.</div><div><br></div><div>Hopefully the above is sensical.</div><div><br></div><div>Mark<br><div><div><br><div class="gmail_quote">

A1: When I had the symptoms you are describing it was because the instance never managed to boot from the image, and was just spinning cpu cycles displaying a "could not boot disk" type message. I figured that out by connecting to the VNC console of the instance. IIRC, you can look through the nova logs to figure out what VNC address to hit for the instance.<div>

</div><div><br></div><div>What may be wrong?</div><div><br></div><div>Q2. When I do succeed to setup the environment, can anybody to point me to documentation on how to write simple code for OpenStack? Something along the lines of "Hello, world!", but using some features peculiar to cloud applications.</div>
<div><br></div><div>Q3. I have no technical knowledge about the cloud at all. Can anybody suggest a learning path so that I quickly can gain the basic necessary general and specific knowledge to start coding (i.e. first read the code and know what's flying, then fix some bugs, etc.)?</div>
<div><br></div><div>Thanks in advance, -Aron</div><div> </div><div><br></div><div><br></div><div><br></div>
