Hello, When I create instance, I want to choice host node. I saw that by default, VMs are scheduled by filter scheduler which only consider computing resource. I want to apply substrate network considered scheduling algorithm on OpenStack. To do this one, I have to monitor utilization of computing/network resources. Now, I’m planning to use OpenvSwitch commend to know network situation.

Do you have any comment for me? (monitor/scheduling)

Try to use Devstack and use your scheduling algorithm.

You can use a script to see which node has resources, specify compute node and 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.
