of the stock method for setting up devstack with XenServer).<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">There is a script at
<a href="https://github.com/citrix-openstack/qa/blob/master/connect-devstack-local.sh">
https://github.com/citrix-openstack/qa/blob/master/connect-devstack-local.sh</a> - download this to the devstack instance you want to just run compute services, and run it passing the IP address of the devstack that hosts the rest of the services.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If you’ve got a split of where the other services are, check out the details in the script – it’s actually quite simple to change hosts in the localrcs.<o:p></o:p></span></p>

compute services.<o:p></o:p></span></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I was having trouble configuring a XenServer Node into an computer Node, the tutorial/devstack are all for using XenServer as a single allinone node.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">For example, I found this really nice VM image from citrix at:<o:p></o:p></p>

</div>
<div>
<p class="MsoNormal">which includes pre-build XenServer patch and images. I can just import them into XenServer and everything works.<o:p></o:p></p>
</div>
<div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<div>
<p class="MsoNormal">Is there any easy way to turn this AllInOne XenServer Node into just a compute node? Of course I have another machine works as the controller node, installed following the OpenStack installation guide.<o:p></o:p></p>
