This patch implements the terremark driver for deltacloud core. I've been using this for a few days to create and manage instances and seems to be fine (deltacloudd -i terremark). Besides this patch you also need the gems 'fog', 'nokogiri', 'excon' (gem install [name]).
Known issues: - getting list of images is slow and sometimes you need to refresh browser manually - still dont get full details about an instance (e.g. os, memory, cpu) - this is an issue with the underlying fog library which I'm looking at
If you would like to play with the driver I have a limited account (20 something days left) that terremark gave me for testing - ping me and I can give you login details. You can use terremark's web management console to confirm what you've done etc: https://my.vcloudexpress.terremark.com/Signin.aspx
