You will need to switch to one of the other schedulers to do this. You can set them up in different zones and use the zone scheduler. Or, as an admin, you can use SimpleScheduler and use -z zone:<host> to send it to a specific host. --scheduler_driver='nova.scheduler.zone.ZoneScheduler or -scheduler_driver='nova.scheduler.zone.SimpleScheduler On Apr 7, 2011, at 1:53 PM, arturo lorenzo wrote: > New
