virtualbox - Failed to load VMMR0.r0 (VERR_SUPLIB_WORLD_WRITABLE)

Question

After I create a new Virtual Machine, when I start it, it shows following error:

Failed to open a session for the virtual machine Milad.

Failed to load VMMR0.r0 (VERR_SUPLIB_WORLD_WRITABLE).
Result Code:    NS_ERROR_FAILURE (0x80004005)
Component:  Console
Interface:  IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

My OS is ubuntu 14.04(64bit) Desktop with gnome.

I read this answer, but I can't understand what should I do.

Solution 1

i had the same issue on ubuntu 14.04 (64bit) i just uninstalled it form /opt/Virtualbox

by running the ./uninstall.sh and installed the new version 4.3.18 and it ran perfect

Solution 2

As alternative, you didn't need to reinstall it, just change the file permission of VMMR0.r0.

sudo chmod 755 /usr/lib/virtualbox/VMMR0.r0 

That's work for me on VirtualBox 5.0.12 Ubuntu 14.04.

Terrible idea to make it 777 if 755 works.

I'm not saying it doesn't work: What I'm saying is that you should give someone a key to your front door if they want to come in, not remove the lock entirely!
