Subject: SV: Is there any open source project support virtual machines

I would recommend you to take a look at the linux-vserver project
(http://www.linux-vserver.org/). It's a very clever way to run vm's without
having to actually install a whole bunch of OS'es on the hosts. It can
utilize most of the hosts system files, require very little resources, and
are very secure (trust me on this one, we use it to run wargames that people
are meant to break levels (but not root, and noone ever has) off.) It's not
possible to break out of the jail by any known method (yes, they fixed the
well known chroot breakout).

As for, I would guess, your main concerns, stability and performance, I
think you will find linux-vserver to fully live up to any expectations you
might have. Networking can be set up through interface aliasing, allowing
your machine to hold as many ip-addresses as there are vservers (+1 for the
host), thus from a networking point of view, looking like a lot of boxes.

As for traffic simulation, I would advice you to set more specific demands
before looking for projects that do this. What kind of traffic will you
need? If you're mainly interested in standard traffic, like http/ftp and the
like, you should be looking for crawler software (or write your own, it's
really not very hard to write a fully functional webcrawler).

Good luck with the project
(And no, I'm not in any way affiliated with the linux-vserver project, but
is using it, and have fallen for it's superiority over other projects, such
as UM-linux)
