[one-users] Self-service Cloud View use case

[Steven Timm]

FermiCloud does something quite similar to what you are asking
for below, although we are currently using an earlier version
of OpenNebula.

The persistence of images and the persistence of IP addresses
are controlled independently in OpenNebula.  Typically for
our fixed-ipVM's we do have a separate image for every
user and each one of those images is marked "persistent" in the VM store. 
but we also have a standard image that anyone can use, with fixed
IP or with dynamic IP.. if the user then wants to make modifications
to their image and store their image, they can do that.

If you need more details, you can email me privately.
