vim.fault.NoHost when deleting standard vswitch

[umarzuki]

Call "HostNetworkSystem.UpdateNetworkConfig" for object "networkSystem-9" on vCenter Server "localhost" failed.

Above error appeared when I tried to remove a standard vswitch or vmkernel

Is this related to vCenter resolved as localhost? How do I change it to its IP?

First I would restart the management agents on the ESXi hosts and try again.

Let us know if this helps or not.
