You can add those disks in your ERB templates (i.e
new_occi_template.erb) using the same OpenNebula template syntax. OCCI will
merge the information provided in those templates and the parameters
provided by the user using the common.erb template.

You can use a persisten image but you can start only one instance per image.

You can only create ranged networks using Self Service, but you can use
fixed/ranged networks in your templates. Also you can create fixed networks
through sunstone and make them available to the self service users, hence
they can select them in the compute creation. However you cannot select a
specific IP. The OCCI API allows it but the self service does not expose
it.

You can open a feature request in our dev site [1], and we can consider it
for the next release.
