I attended a presentation by some of the Cloudstack guys the other week and, after the talk, someone mentioned that Citrix is having a hard time rolling OpenStack and Cloudstack into one product so they've migrated away from OpenStack and have put those resources on Xenserver and Coudstack.
The guy said that "OpenStack lost their #2 contributor [Citrix]". I can't find any confirmation of this online, though. Does anyone else have any insight? We're struggling with choosing which platform to use for our private cloud (OpenStack vs Cloudstack). Confirming whether OpenStack has actually lost support would make a big difference.
