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.

Thanks!

Hi Dhanesh,

Yes, this should be possible – there is no additional coupling between the compute node and the network node when running with XenServer and as such they can easily be running as two separate virtual machines.

In terms of the setup, you might want to look at http://blogs.citrix.com/2013/06/14/openstack-networking-quantum-on-xenserver-from-notworking-to-networking/ which has a useful deployment diagram and should help explain what can be separated in which way.

Hi All,


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?

Dhanesh M.
