When an OrgVDC has tenancy enabled, the network pool cannot be selected or updated. This is because the OrgVDC will use the network pool backed by the systemwide default overlay Transport Zone in the backing network provider.
The same behavior is reflected in the OrgVDC creation wizard. If “networking tenancy” is enabled, the option to select a network pool will be unavailable. Disabling it, however, allows the user to select from available network pools.
This change was implemented as part of enhancements to support Networking Tenancy.
It is expected behavior in vCD when using network-tenancy.
