[Users] Creating Logical Network issue - API

Hi , I'm trying to create Logical Network and assign it to cluster & want to bond this to one of the Network Interface on Host. so that i can isolate my VM from other networks. The issue is even if i set Cluster while creating Logical Network, it is not setting the cluster. In Web Admin it is in unset state. Also, let me know how do i bind this Logical network on Host Interface. *Java code:* Network nw1=new Network(); VLAN vlan = new VLAN(); vlan.setId(2000); nw1.setVlan(vlan); IP ip = new IP(); ip.setAddress("192.168.1.151"); ip.setGateway("192.168.1.1"); ip.setNetmask("255.255.255.0"); nw1.setIp(ip); nw1.setName("apiNetwork"); nw1.setDataCenter(api.getDataCenters().get("testDC")); nw1.setCluster(api.getClusters().get("testCluster")); org.ovirt.engine.sdk.decorators.Network nw2 = api.getNetworks().add(nw1); -- Thanks & Regards Tejesh
