I'm doing that right now, but just using LinuxCOE the way it is,
downloading the ISO image generated and providing it as an input to my
Project-Builder tool, using the newvm option.

Details: http://trac.project-builder.org/wiki/NetPerfExample
(Look for newvm)

I do that on a Dual Core2Duo server with 2 GB of RAM.
No pb.

Indeed: du -sh /users/qemu/
118G    /users/qemu/

No !!

No again. IMO, the best approcah is to use the external commands
provided by each tool to handle the VMs. For the moment, I work with
QEMU/KVM so that's what is supported, but placeholders exist to add
support for other techno (Xen, VMW* if they provide the right tools, I'm
less concerned by non Open SOurce solutions myself)

A lot :-)
