[one-users] Creation of templates by cloud users in Sunstone 4.2.0 views

[Gerry O'Brien]

Hi Daniel,

     I have already created templates for cloud users but that does not 
allow them, as far as I can see, to make persistent images. In any 
event, the freedom to mix and match CPU/Memory/network settings to 
various images is lost.

    Also, without the ability to create templates I cannot see how they 
can create a datablock and install their own images from CD. I can 
enable templates in the cloud view but as they are not controlled by 
quota I'm worried about not being able to access our sysadmin templates 
among an unbounded clutter of user templates. If the user templates 
could be stored somewhere else or hidden from view that might solve the 
problem.

    Using the CLI is not really an option as I had intended to make the 
self-service available to undergraduate students. In my experience, even 
researchers who had previous cloud experience found the OCCI interface 
unintuitive at first. However, once they got the hang of it, it proved 
very flexible.

     It seems strange to release a new version of software and cripple 
functionality that was previously available (Microsoft's Windows 8 come 
to mind!). Can OCCI 4.2 be built from source with the UI included or the 
version of OCCI shipped with 3.8 pointed at OpenNebula 4.2?

     My intention was to deploy 4.2 for student use this week. If I 
can't provide the functionality of OCCI 3.8 I will have to abandon 4.2, 
which seems a shame.

             Regards,
                 Gerry
