Description of problem: Once a migration network has been selected for a VMware host, it is only possible to select another network as migration network, not reset to no migration network. It is possible that the users have invalid credentials and that until they retrieve valid credentials they want to fall back to the default behavior, i.e. connect to vCenter and use the management network. And this is currently not possible. From a technical point of view, this would mean deleting the Host CR.
This should be part of build 2.0.0-8 / iib:62459.
Added to docs
@fdupont i am not sure about the expected behavior. The only way to remove the host configuration is to delete the host CR (api), as you say. In The UI, it is only possible edit the host. If this is the case, than this BZ can be set to verified.
@amastbau, the UI does have this capability. When you select the Management Network as the network for a Host, the UI just deletes that host CR instead of editing it.
build 2.0.0-8 / iib:72981
