• \[SOLVED\] virtualbox does not work


    for installing virtualbox, i installed virtualbox, virtualbox-host-modules and virtualbox-host-dkms packages and added my user to vboxusers. virtualbox worked fine but needed to run “modprobe vboxdrv” command before i run it. so i installed dkms and used “systemctl enable dkms.service”. again i had the problem. using “systemctl status | grep dkms” i found that the dkms is not started because it linux-headers is not installed. i installed linus-headers and restarted the computer. now virtualbos starts, but when i start the hosted os (winxp), i get the message error:

    Failed to open a session for the virtual machine WinXP.  
    Failed to load VMMR0.r0 (VERR\_SUPLIB\_OWNER\_NOT\_ROOT).
    

    and the detail is:

      
    Result Code:   
    NS\_ERROR\_FAILURE (0x80004005)  
    Component:   
    Console  
    Interface:   
    IConsole {db7ab4ca-2a3f-4183-9243-c1208da92392}  
    
    

    i searched the web and found that most of people got this message because the owner of /usr/lib/virtualbox is not root, but for me it is correct.

  • the problem is that /usr should have root ownership and probably virtualbox change it. i changed the ownership of /usr to root and the problem solved
