<div>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).</div>
<div><br>
</div>
<div>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.</div>
