Historically CloudStack has used Xen and XenServer interchangeably to refer to any XenAPI based implementation. With the recent release of Xen Project 4.4 (http://blog.xen.org/index.php/2014/03/10/xen-4-4-released/), and interest in alternate architectures like ARM, the loose definition of our Xen support could be confusing. In this two part effort I propose that CloudStack 4.4 be cleansed to ensure that all Xen references become XenServer references, and second that an alternate hypervisor type of "XenProject" be introduced for pure Xen which could either support libvirt or libxl (preference for libvirt given the 4.4 work to improve the interface and broader support for libvirt in general).
