OpenStack Compute (nova)

In a multiserver environment can you run an instance on an specific compute node

Asked by arturo lorenzo

I have three boxes. One is the CC and two are compute nodes. Can I send instances to either compute node? What is the scheduling algorithm?
Thanks!

There is a Scheduler Service that has Scheduler plug-in's (drivers) to decide where to route.

Currently the default is the ChangeScheduler which randomly picks a Compute node.

The Zone work going on in https://blueprints.launchpad.net/nova/+spec/multi-cluster-in-a-region will expand this do Server-Best-Match based on Compute load.

Hope it helps!
