Hi All, 

I am trying to setup a multinode setup for openstack 
One controller, one compute and network node. 

I am just not able to decide which option I should choose on the installation part of controller and compute node openstack. 

There are two options which I have read are given below 1 first
2 second 
My requirement is it will be initally a POC and then it will be deployed . 
Please suggest, or if something more better option, I dont want to experiment with yaml still. 
thanks in advance

 Yes, for what it's worth, we manage all our public cloud regions with instances running on XenServer in a small private cloud.  That small installation is managed by Vms manually created on a small number of XenServer machines.  This includes Quantum and Melange nodes (although we hope to move them to Neutorn soon).
Additionally – our compute nodes run in production as a VM on each XenServer hypervisor.  It doubles the overhead from a "node" standpoint, but provides a lot of advantages.

Is it possible to use Xenserver with  two virtual machines as Compute Node and Network node? Will it effect the performance? or the set up in any ways?
