CloudStack and the new XenServer licensing model
Citrix have announced that as of XenServer 7.3, the free version (including the ‘opensource’ version packaged by Citrix) will no longer have feature parity with the paid-for Standard version.

CloudStack CA Framework | CloudStack Feature Deep Dive
Introduction The CloudStack management server listens by default on port 8250 for agents, and this is secured by one-way SSL authentication using the management server’s self-generated server certificates.
