I am trying to start a Ubuntu (64-bit) Linux VM from VirtualBox (5.2.18 r124319 (Qt5.6.3)) on macOS High Sierra (10.13.6 (17G65)) running on a 2016 MacBook Pro 15"

The MacBook Pro in question is recently restored using my Time Machine Backup. I have enabled FileVault on the original MacBook Pro.

Here is the image of the error dialog box:

enter image description here

The text is:

Kernel driver not installed (rc=-1908)

Make sure the kernel module has been loaded successfully.

where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

I have enabled disk level encryption when I set up the Linux VM.

Here is some more details of the VM

It is what I picked up from the system.log

Sep 26 10:15:44 konga-mbp-loaner com.apple.xpc.launchd[1] (org.virtualbox.startup[95]): Service exited with abnormal code: 1

What I tried after the Linux VM failed to start:

  • I tried to reinstall VirtualBox but the installation failed.
  • Restart the machine and try reinstall again, also failed.

  • The reinstallation of VirtualBox failed or of the VM after reinstalling VirtualBox? – Nordlys Jeger Sep 26 '18 at 1:00
  • The reinstallation of VirtualBox failed. VM failed to start even before the attempt to reinstall VB – Anthony Kong Sep 26 '18 at 1:17
  • And the error (rc=1908) is popping up when? – Nordlys Jeger Sep 26 '18 at 1:19
  • At the very beginning when I simply wanted to start the linux VM. – Anthony Kong Sep 26 '18 at 1:19
  • So your problem now is not a failed VM, but a failed VirtualBox installation, so you should try to resolve that first. (It could be, that I'm completely missing the point of the question) – Nordlys Jeger Sep 26 '18 at 1:22

Basically it is because Apple has blocked some extensions from loading. After unblocking them I can reinstall VB as expected.

    I'm having the same problem, but I have no Allow... button in my Security & Privacy dialog, I've unlocked with the superuser account, I've uninstalled VirtualBox several times and tried again, no luck...what can I do? – SPlatten May 14 at 10:14
  • Did you pick the 'App Store and identified developers' option under 'Allow apps downloaded from:'? – Anthony Kong May 14 at 10:44
  • Sorry, yes, please take a look at my post superuser.com/questions/1436347/… – SPlatten May 14 at 10:47

Make sure that you move the old .app to trash before re-installing virtualbox. Check Security & Privacy as mentioned by others in case it was locked out by the system.
