Using Finder, I right-clicked on the /Applications folder, selected Get Info and then changed the permissions for "everyone" (bottom of panel) from "Read & Write" to "Read only".
My VM started after that.

Repairing permissions in disk repair also fixed my issue. Thanks!
Re: Failed to load VMMR0.r0 (VERR_SUPLIB_WORLD_WRITABLE)
I had this error as well, specifically in the log file it said:
Oracle VM VirtualBox Extension Pack (Version: r0; VRDE Module: unusable because of 'The owner is not root: '/usr/lib' (rc=VERR_SUPLIB_OWNER_NOT_ROOT)')
pdmR3LoadR0U: pszName="VMMR0.r0" rc=VERR_SUPLIB_OWNER_NOT_ROOT szErr="The owner is not root: '/usr/lib'"
In my case I just had to change the permission of /usr/lib back to root. I had run a library installer which had to be run as root and it changed the permission of that directory. It seems Virtualbox requires the path to its libraries be owned by root.
cheers,
Dan

Thanks Johnnyu, for me changing permissions as you describe fixes the problem. And problems with the disk shown by DU do not matter to VirtualBox.
Also, VB folks, you have a lot of work to do improving this error message, and any others worded like it.

One- when I ran Disc Utility It reported 197 pages of "incorrect settings" I thought this to be suspicious because the IMAC has been running with minimal problems. I wasn't going to to run it to make this many "corrections". Additionally, I saw no responses to this advice that said it worked.
Two- I researched Mac rumors and there was a suggestion to use the console to reset permissions. Others with the same issue verified that it worked. Being unsure of the terminology and the criticality of the command syntax, and reading different information for different OSX versions I went to the two directories affected /Applications and /Applications/VirtualBox.app and checked their permissions through finder by using COMMAND-I. I set all permissions (system, admin,and everyone to "Read only" )in both directories.
It works now!!!!!
My present OS is 10.6.8 I suspect that the last update ( allegedly a preparatary step for the installation LION) reset these permissions.
Who knows it may not work tomorrow!
