I had Virtualbox setup and working fine until I upgraded from KDE 4.8 to 4.9. Now I get the following messages:
Failed to open a session for the virtual machine wind7.
The virtual machine 'wind7' has terminated unexpectedly during startup with exit code 1.
The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing
as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.
Can someeone help me?
