This has nothing to do with VirtualGL. If there are two X servers running and you are able to successfully run GLX apps on both simultaneously, then VGL will "just work" as long as you set VGL_DISPLAY properly. However, getting two X servers running and being able to successfully run GLX apps on both simultaneously is the trick, and AFAIK, the current hardware-accelerated 3D drivers from nVidia, etc. don't allow it. There may be other O/S-level things that disallow it as well. But then again, even though I'm the developer of VGL, I am actually not the foremost expert on using it in a multi-card environment, so others on the list may be able to provide a better answer.
