<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I would personally recommend using XenServer 6.2 as that is fully open source and includes features such as the live storage migration in the free version.
XenServer 5.6 is now very dated.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The “No host is available” is simply a message that says the controller node has not been set up properly – although it’s not clear from your nova.conf snippet
why that is. You’ll need to check the output produced by Nova to see what the error in connecting was. It might be to do with network setup, or the username/password details.<o:p></o:p></span></p>
