First I tried to start, it failed and said the same thing I had in 11.4:
Kernel driver not installed (rc=-1908)
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
‘/etc/init.d/vboxdrv setup’
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.
But in 11.4 executing ‘/etc/init.d/vboxdrv setup’ worked. In 12.1rc2 it doesn’t, I got an error telling me that there was no KERN_DIR specified in the /var/log/vbox-install.log
I googled around and installed
Installing: kernel-devel-3.1.0-1.2.1 [done]
Installing: kernel-desktop-devel-3.1.0-1.2.1 [done]
However it’s still not working, now the log says this and I don’t know what to do next:
