You could enable the images tab, as you did in another thread, so users can
create their own images and in the "launch" vm button they will be able to
select those images and one of the predefined templates, which includes de
cpu, memory, network configuration.

You can use the base template, instantiate a new vm and then attach a new
disk (datablock) where users will install their own images from CD.

I don't really get what you are trying to accomplish, could you please
explain your use case, so we can see if it fits in the new cloud views.
