Well, the usual answer for nested X sessions is Xephyr, which supports extensions including GLX, but only software rendering is supported. 10 years ago, an Intel employee forked Xorg to provide hardware accelerated Xephyr, but it's pretty dead nowadays. Even if you could compile it, I doubt you'd be able to load the current nvidia driver into it.
