Hello Debianuserforums,
I currently installed Oracle Virtual box to my Debian "Stretch" Machine (Cinnamon).
Initially I followed the instructions from the link below to install Oracle Virtual Box 5.1
https://backports.debian.org/Instructions/
I plan to install another Debian as a guest VDI image in Oracle Virtual Box. Followed the on screen instructions in creating the image in Oracle Virtual Box.
However, when I try to boot the image to proceed with the installation, I keep on getting this error:
Oracle VirtualBox 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
'/sbin/vboxconfig/'
as root.
where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.
I executed vboxconfig, encountered a message that "modprobe vboxdrv failed…"
I uninstalled Oracle VirtualBox 5.1 and installed 5.2 but I keep on getting the same error.
I ran the dmesg command and got the following message:
vboxdrv: disagrees about version of symbol cpu_tlbstate
vboxdrv: Unkown symbol cpu_tlbstate (err-22)
I've tried multiple solutions I've found from the internet but none is working.
Thank you for your help!
