This is close to all i need.
I did upload the iso as image.. but how do you attach it to the VM ? I assumed that
issue was a 4.4 changes / constrain.
It was a miss-interpretation on my part that ISO use was relegated to being only as a
"volume" independent.
As such.. I went back to uploading iso images. They are now "images" in disk.
Going to VM: select vm -> Disks -> VM Devices -> "edit virtual machine"
-> Boot Options -> "attach CD" -> "whoot!!!"
ISO images now show as attachable option.
Thanks.. All good.
