This error seems to be popping up with Lion and Oracle VirtualBox
Failed to load VMMR0.r0 (VERR_SUPLIB_WORLD_WRITABLE).
Unknown error creating VM (VERR_SUPLIB_WORLD_WRITABLE)

Some users get this error because /usr is world writable. I checked mine, it was ok. Also went through Disk Utility and repaired permissions. Also set the .vdi file to 755. No luck

I then changed /Applications and /Applications/VirtualBox.app to 755,

#sudo chmod 755 /Applications
#sudo chmod 755 /Applications/Virtualbox.app

Works now (I also upgraded to latest .app and extension file)

I have no idea why these files are set world writable!
