<p class="MsoNormal"><span style="font-size:10.5pt;font-family:"Calibri","sans-serif";color:black">To Bob's point, I was able to follow these instructions in the past week and successfully get XenServer 6.2 up and running. The only caution I would give is
that buried in there is a link to "XenServer and DevStack". While it does build a working running devstack, the branch of nova is not the master. When I ran the unit testing on the branch many unit tests failed. It's a relatively easy fix to move to the
master, which to this point has not had any issues for me (though my testing has been limited).<o:p></o:p></span></p>

<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.</span><span style="color:black"><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.</span><span style="color:black"><o:p></o:p></span></p>
