<p class="MsoNormal">Hi,<o:p></o:p></p>
</div>
<p class="MsoNormal">I'm completely new in OpenStack's Universe and I need to understand a lot of things!<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Bust let's start with a couple of questions.<o:p></o:p></p>
</div>
<p class="MsoNormal">1. I have installed OpenStack using DevStack in a physical machine (I have already an Ubuntu system). At the end of the installation there was written the address where I can open Horizon (e.g. 10.1.115.126). What happens if I connect my
laptop from another network? Does it remain the same? Or should I do a specific configuration?<br clear="all">
<o:p></o:p></p>
<div>
<div>
<div>
<div>
<p class="MsoNormal">2. I will work with nova in particular, especially in the scheduling part. I would like to know where the scheduler take the information about the state of the host to assign it after the filter & weight.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I think that those parameters about the status of the host are memorised in the database, but it's only my hypotheses, I haven't read anything about it.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">And if it's so, how are collected those information? By who?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Sorry if I did some silly question, but I would like to well understand the basis.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Let me also know if exist a good guide that explains how to start with OpenStack from zero!<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Thank you <o:p></o:p></p>
