[Users] Delete & Detach Logical Network

[Tejesh M]

I tried below code, but still it is not detaching the network

          HostNICs nicsApi = api.getHosts().get("venus-vdsb").getHostNics();
          List<HostNIC> nics = nicsApi.list();
          HostNIC nic =
api.getHosts().get("rhevhost").getHostNics().get("bond1.1231"); //logical
network network name is "testLNw"
          nic.setNetwork(null);


*Result of executing this line*:
nicsApi.setupnetworks(createSetupNetworksParams(nics));

*Result:*
code  : 400
reason: Bad Request
detail: Cannot setup Networks. The following VMs are actively using the
Logical Network: greyvm, vmLogicalTest1, OmVM1. Please stop the VMs and try
again., Cannot setup Networks. The following Bonds consist of less than two
Network Interfaces: bond0., Cannot setup Networks. The following Network
Interfaces were specified more than once: eth0, eth3, eth1, eth2.

Can you post the complete code?
