If you just installed the newer kernel, you still need to reboot so that your system will boot up with this new kernel.

It looks that when we install virtualbox 5.1.8 on top of windows 7. It cannot run a VM which installed a Fedora 24 workstation.

[root@localhost ~]# virtualbox
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
available for the current kernel (3.11.10-100.fc18.x86_64) or it failed to
load. Please recompile the kernel module and install it by

sudo /sbin/rcvboxdrv setup

You will not be able to start VMs until this problem is fixed.

If you can help me I’d be very thankful

My specs:
4.9.12-200.fc25.x86_64 (Fedora 25)

I uninstalled everything and follow the steps in this tutorial, but when I open the VB to start a VM I’m getting the following error:

RTR3InitEx failed with rc=-1912 (rc=-1912)

The VirtualBox kernel modules do not match this version of VirtualBox. The installation of VirtualBox was apparently not successful. Executing


may correct this. Make sure that you do not mix the OSE version and the PUEL version of VirtualBox.

where: supR3HardenedMainInitRuntime what: 4 VERR_VM_DRIVER_VERSION_MISMATCH (-1912) – The installed support driver doesn’t match the version of the user.
