Description james labocki 2012-01-16 16:10:03 UTC

Description of problem:
If a user creates a new virtual machine from a template that is using a pre-allocated disk in the "resource allocation" section the only option for the "disk" when "clone" is selected for "provisioning" is "preallocated". There should not be a dropdown list if the only option is "preallocated". 

On a side note, the "create new virtual machine" dialogue "resource allocation" section should show the details of the template disk so a user knows what template/disk they are using as a basis for the VM.

Since behaviour across the application should remain consistent, general question is: when a drop-down contains only one option, should it be disabled/hidden/shown as a label/etc. -> changing the subject accordingly.

I think it really depends if you want the user to be informed about the choice we've made for him or not.
An example where it's useless: when you have two hosts (the minimum for migration - but also very popular in POCs), and you migrate a VM from one hosts - there's really no use of asking to which host you'd like to migrate to - you are going to migrate from host 1 to host 2. Therefore, the whole dialog should not even pop up.

It also matters if it's something that can be somehow changed later on or not.
So we need to set guidelines, and treat each specific case separately, probably.
