@sgratch This is the current full warning message in the documentation:

It is strongly recommended to create a VMware Virtual Disk Development Kit (VDDK) image in a secure registry that is accessible to all clusters.

Text below text box: "The VDDK image is empty. It is strongly recommended to provide an image using the following format: ... "
