Re: [openstack-dev] [nova] is there a way to simulate thousands or millions of compute nodes?

@Michael Okay, focusing on 'thousands' now, I know 'millions' is not good metaphor here. I also know 'cells' functionality is nova's solution for large scale deployment. But it also makes sense to find and re-produce large scale problems in relatively small scale deployment. @Sandy All-in-all,

I would say that supporting millions of compute nodes is not a current priority for nova... We are actively working on improving support for thousands of compute nodes, but that is via cells (so each nova deploy except the top is still in the hundreds of nodes). I worry about pursuing academic

Hi all, Is there a way to simulate thousands or millions of compute nodes? Maybe we could have many fake nova-compute services on one physical machine. By this other nova components would have pressure from thousands of compute services and this could help us find more problem from large-scale
