You have to reboot the host to get the kernel module to load.

Do you mean just reboot your mac? I have the same problem, tried rebooting mac and still had same problem, also tried allowing full disk access that didn't work either?

Have you tried the proposed 'solution' discussed in tis thread: viewtopic.php?f=39&t=98763&start=75

Sorry, can't offer any personal experience, as I have VirtualBox 6.1.16 working fine on 2 separate Big Sur installations and haven't experienced any problems with installation or running VMs.

Did you re-install Virtual Box following the system upgrade?

Having gone through this myself:

- Install Virtual Box
- In System Preferences -> Authorise application from Oracle America
- Restart
- Start Virtual Box & a VM
- Take heed of the change needed in system preferences for key strokes

You can see here too: https://stackoverflow.com/questions/539 ... -installed

From what I can tell this is due to extra security that has been added around kernel level drivers.
