Hi all, I'm new to openstack, I read the manual to study about it's scheduling.
I find that there are other schedulers (chance, multi, and simple scheduler). How can I config to change the schedule in nova? By default there is "compute_scheduler_driver = nova.scheduler.filter_scheduler.FilterScheduler" in nova.conf file. It will call host_manager to apply all the filters (RetryFilter, AvailabilityZoneFilter, RamFilter,...) is defined in there right? and so we just change those filters if we want to archive our requires? I just try to find how to allocate an instance. For example, we want to create 2 instances both are require lot of CPU, it will be allocated in two different hosts. In case of one is require CPU, and another one is just require I/O, it will be allocated in the same host. Any idea? thanks, -- Regards, Nguyen Quoc Vu
