You can configure your VMware region to connect to a resource pool.
resource_pool = <cluster_name>:<resource_pool_name>
where <cluster_name> is
the name of the VMware cluster where the resource pool is defined.
When you specify a cluster name and a resource pool name, the resource
pool under the cluster is the target to deploy the virtual machines.If you have multiple resource pools in the same cluster, you can connect to a different resource pool for deployment by creating a new host aggregate with a procedure similar to Connecting to different datastores in the same cluster and specifying different resource pools with the resource_pool variable in the new OpenStack Nova Compute service configuration file related to VMware.
