Usually a result of 60 FPS indicates that OpenGL is locked to the vertical
refresh rate of your video card or monitor. The 101 FPS indicates it isn't
locked to vsync inside the VM, but is using software rendering while you're
probably using direct rendering outside the VM which apparently does vsync
by default now.

If you run the "real" glxgears from a terminal window, do you get "Running
synchronized to the vertical refresh" on standard error?
