<p class="MsoNormal">Hello!<br>
<br>
First of all I want to say, that aggregate function isn't working at all, but it is solved by this post:
<a href="https://ask.openstack.org/en/question/8392/aggregate-hosts/">https://ask.openstack.org/en/question/8392/aggregate-hosts/</a><br>
After fixing sources aggregate is working now, I can add master and second host to pool (second host's node-compute successfully reboots and host adds to pool).<br>
But after adding second host I got problem with second hosts nova-compute, it won't start:<br>

I discover, that I can't set up nova-compute on "second host" in XenServer pool which is created by XenServer (without OpenStack aggregate), error is same. To master host nova-compute connects successfully. I tested this in two different XenServer 6.2 pools.<br>
Is there some solution how can start to work "second host's" nova-computes?<br>
<br>
Thanks.<br>
