Comment 6 for bug 1593773

This bug in test nsxv_add_delete_nodes. In https://github.com/openstack/fuel-qa/blob/stable/mitaka/fuelweb_test/models/fuel_web_client.py#L704-L724 we set conpute-vmware as target_node_1. target_node_1 used in https://github.com/openstack/fuel-qa/blob/stable/mitaka/fuelweb_test/models/fuel_web_client.py#L704-L724. Vcenter "Cluster1" assigned to target_node_1(compute-vmware) and vcenter "Cluster2" assigned to target_node_2(controller). After delete compute-vmware node - vcenter "Cluster1" reassigned to controller node- that is not supported and causes an error. As a result, the VM starts on Cluster2 (the controller node is not reconfigured), but NSXv configured to pass traffic for Cluster1.
