This VDC does not support the creation of Org VDC Networks. Please contact your system administrator.VMware Cloud Director 10.x
This is an expected behaviour when there is no Network Pool associated with an Organization VDC. When there is no Network Pool associated with an Organization VDC the only type of network that can be created is a Direct Network by System Administrator users.
To resolve this issue add a Network Pool to the Organization VDC.
Note: NSX-T Geneve Network Pools can only be selected if the Organization VDC has a Backing Type of NSX-T. For Organization VDCs with a Backing Type of None, see Create a Network Pool for steps on how to create Network Pools that are not backed by NSX-T.
