If I leave the KDE composite option as XRENDER, I can open up to 6 VMs without any freeze. All of them with 2 CPUs, 3D accel enabled an all. But all I need to do to freeze the machine is to start ANY OpenGL app and let it run for about a minute. It can even be one of the GL screensavers. It is a guarantied freeze ! I have tried all sorts of combinations: nvidia.ko last, vboxdrv.ko last, no linux.ko, with powerd, no powerd, etc..., etc... No matter what, if it involves OpenGL, bang !! if it doesn't, it's OK. What I also noticed, monitoring my machine from another terminal on the LAN (systat -vm 1) is 200K in page faults at the freezing moment and free memory on gkrellm is practically zero, no matter if I have 1 or 6 VMs running. I can't say if it is KDE, Vbox or nvidia because not even ping from the remote terminal works. Other than that, It works great.
