Yes, based on filtering (VCPU, RAM) of scheduling algorithm, Nova scheduler will decide which compute host to be used for VM. However please find below the steps to force an Instance onto a host.
nova boot --image <uuid> --flavor m1.tiny --key_name <> --availability-zone nova:serverx
Note: I think the above command can be run only by users with admin role. serverx is the name of the hypervisor host, which we can get by running the below command.
nova hypervisor-list
Thanks.
In short answer, Nova-Scheduler will use filtering and weighing to decide which compute host will provision the new vm instance.
In details,just check this link http://docs.openstack.org/developer/n... .
Hope that helps!
