Cant start VM under ubuntu 11.04

Post by sreda »

Hi,

I have just installed Ubuntu 11.04 and VirtualBox 4.0.4.

I have imported a VM I was using in another pc, and I have created a new VM with same result: When I start i get the following error, and after much searching in the forums have not been able to find a solution. Seems to be a permisions related issue, but cant find what...

No s'ha pogut obrir una sessió per a la màquina virtual *********.
Failed to load VMMR0.r0 (VERR_SUPLIB_WRITE_NON_SYS_GROUP).
Unknown error creating VM (VERR_SUPLIB_WRITE_NON_SYS_GROUP).

Component: Console
Interfície: IConsole {515e8e8d-f932-4d8e-9f32-79a52aead882}

The log reards as follows:

The reason for this error message is the following: VirtualBox is installed into a certain directory, in your case in /usr/lib/virtualbox. One section of these directories is owned by a non-system group which has write access to this directory. In other words, a non-system user could change the content of one of these directories (either /usr, /usr/lib or /usr/lib/virtualbox). This is a security risk, therefore VirtualBox refuses to start. Fix the permissions of all these directories.
