Hello,

First of all, I appologie about my possible not perfect argumentation and my
English skills which are even less than that ;-).

I would like to say why I think MOM (Not MOM directly, but the problematics MOM
is dealing with) is very important to Fedora and very important for futures and
moderns virtualization systems.

Actually there is simply not a lot of real solutions to deal efficiently with
memory overcommitment. Ballooning and KSM truly working great independently,
but together they are sources of many problems and configuration's
complications.

There is a real need of memory overcommitment management systems and MOM is
maybe not the best one, but it's working well and is available.

As fedora say in its values "Features First" and (I think) as a "new
technologies innovator" being able to purpose to its user an "advanced and
efficient virtualization environment" is a necessary objective. A tool like MOM
and in a more general way, a working solution to the issues of memory
overcommitment in virtualization can be a real and great advantages to Fedora.

Another point, today we are dealing with the "green" and the green by one of
its definitions mean to use hardware efficiently and to be equipped in a
well-balanced manner compared to its need. In this case, be able to deal with
memory will help running as many virtual machines as possible (and keeping them
working properly, qa, etc.) on a single system.

Of course there is also the question of the CPU overcommitment (which tools
like niceload or simply nice gives basics workaround, but they are realy not
perfect to solve that kinds of problems) still need to be solved.

And for all this reason if someone would like to help this project to grown by
giving it a chance to be in the fedora world I would be truly grateful to him.

A MOM satisfied user

Seb
