I am having an issue. I am building a test case and one step involves adding a network to a NIC object. When I perform this step in the UI by navigating from Hosts -> hostToAttachNetwork -> Network Interfaces -> Setup Host Networks . And I drag the required network to NIC object and press ok, after the operation is complete, an event log is registered in the engine.log containing this text: "Network changes were saved on host" When I perform the same step in the automated test case, using the following code: hostService.setupNetworks().modifiedNetworkAttachments( networkAttachment() .network( network() .id(netToAdd.id()) .name(netToAdd.name()) ) .hostNic( hostNic() .id(hsNicId) )) .send(); The operation is performed correctly, the network is attached to the appropriate NIC, but there is no log registered in the engine.log. I am wondering is there a better way to perform the above task that will register an event in the log file. Or is it possible that this a bug in the SDK? Thanks
