Re: [Xen-users] Xen Cloud questions

[Olivier LAMBERT <lambert.olivier@xxxxxxxxx>]

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.
