<div dir="ltr">Hi all!<div><br></div><div>Just joined the mailing list. I'd like to do some development on the project (probably Nova). Some questions regarding how to start:</div><div><br></div><div>Q1. I'm trying to setup Nova in a virtual environment - <a href="http://uksysadmin.wordpress.com/2011/02/17/running-openstack-under-virtualbox-a-complete-guide/">http://uksysadmin.wordpress.com/2011/02/17/running-openstack-under-virtualbox-a-complete-guide/</a> - on a Windows host. I've successfully started an instance and assigned it a network address:</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>
