I''m using Xen 3.4 on Debian Lenny, and a web interface (still in dev), to have a eye on all the stuff. I saw the Xen Cloud project, but I have some questions about it. Can I summarize Xen Cloud like this : "latest" Xen Hypervisor with "improved" API (OCaml replacing python and more stuff) which enhance informations about all Xen hypervisors in same time, to provide a simple way to watch this. Am I right ? Second question : where can I find documentation about the API, like the pdf in this page : http://wiki.xensource.com/xenwiki/XenApi, but for the new one. Third question : does my current project of web interface (http://xen-orchestra.com) is still relevant for Xen Cloud ? API binding are similar ? And last : when did you think using Xen Cloud is more useful than "simple" Xen, or reverse the question : is still useful to have a "simple" multiple Xen hosts in a network or Xen Cloud is a must have ?

Hello Dave, First of all, thank you for these answers. In fact, the new API seems to be really better, especially for its new class, like VM_guest_metrics (which is not implemented on "classical" Xen). I really need it to provide a best overview of DomU''s in my web app. I presume VM_guest_metrics is operational now (or not ?). About the "glossy marketing and other stuff" names (mandatory now, sorry about that ;) ), there is : - ''Intelligent Space Occupation System'' : feature of the GUI of XO. A simple but so far nice system which balance on each side each Dom0, with their "weight" (number of domU displayed) : it allows balanced display of the page : the idea was given by someone working in GUI, I talk about it here : http://xen-orchestra.com/2009/09/interview-with-a-gui-specialist/ ''First Load Ready'' : it helps to load the page without using JSON (PHP to JS string). For the first load, data are incorporated directly in the page. Simple feature again, but useful to avoid wasting transfers ;) ''Conductor'' : not yet exists, but a project to offer a XO appliance with EcoPool feature (and all the previous features of XO). This "box" will have only a web interface with simple configuration, to deliver a "all in one" package for managing all Dom0''s with XO. ''EcoPool'' : result of a future sort of "joint-venture" with a company specialist in game servers. This feature automatically reduce RAM/CPU part when the server is unoccupied (no game with players ATM, but dedicated still running), and live migrate on a specific pool of servers, in sort of "hot standby" with low resources. Anyway, the project is still young and under heavy development, but recently, my contribution was requested on big projects with XO and new features, so contributers will increase. Furthermore, the "base" is very clean, and display is really separate from the "engine". So, future dev will be not complicated. And we use git :o Regards, Olivier.
