Add new disk on a VMWare VM using Foreman API

Yes it really changed the VLAN of my VM in the vCenter. I’ve tried it on two different vSphere with two differents installation of Foreman, same problem : VLAN are changed (???) but nothing happen to the disk, even when i tried just extending the already existing disk as shown here (How to resize vmware-volume when creating host via api?) which seems to be an easier things to do, but do not work for me. I forgot to mention earlier, both Foreman are running the 1.16.2 version
