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!

Using CLI:

nova boot --image <uuid> --flavor m1.tiny --key_name <privatekey> --availability-zone nova:<name of the compute node>

You can specify name of the compute node.

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 (https://blueprints.launchpad.net/nova...) will expand this do Server-Best-Match based on Compute load.

Hope it helps!
