VM Virtual Box (OpenSUSE 12.1/12.2)

OpenSUSE 12.2

    After installing the VM Virtual Box version 4.2.6, it won't start. In  terminal it displayed the following error: "Failed to open the X display"
    The solution was to recompile the VirtualBox kernel. The following packages are needed:
           kernel-devel
         kernel-source
         gcc
     Than VirtualBox kernel can be recompiled:
         sudo /etc/init.d/vboxdrv setup


OpenSUSE 12.1
 
    After installing the VM Virtual Box version 4.2.0, when I tried to add an existing VM, I came across the following error: “Could not start process Cannot talk to klauncher: Not connected to D-Bus server”.

    The solution for now is to downgrade the D-Bus packages to version 1.5.8.2.1.2/3. To do this, step-by-step:

1. Open YaST>Software Management
2. Search for “dbus”
3. On “dbus-1”, “dbus-1-devel”, “d-bus-1-devel-doc” and “dbus-1-x11” select the option to use version 1.5.8.2.1.2/3. To do this, select the package and on the lower part of the screen you will find the tab “Versions”. There you can select the version you want to be used.
