Answer 1

MAC with BIG SUR -- Kernel driver not installed (rc=-1908)

Make sure the kernel module has been loaded successfully.

where the error is:

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

Download and install the latest VirtualBox 6.1.18 or higher. And then follow the below steps to resolve.

Step 1 - run:

sudo kextload -b org.virtualbox.kext.VBoxDrv 

Step 2: Go into System Preferences->Security & Privacy

Step 3: Unlock the security center

Step 4: Approve the software by Oracle

Step 5:

sudo kextload -b org.virtualbox.kext.VBoxNetFlt sudo kextload -b org.virtualbox.kext.VBoxNetAdp sudo kextload -b org.virtualbox.kext.VBoxUSB 

Step 6: Reboot

Answer 2

Registering the .kext directly via terminal solved this issue for me.

sudo kmutil load -p '/Library/Application Support/VirtualBox/VBoxDrv.kext'

There should be a prompt in System Preferences to allow the kernel, which will require a reboot.

Reboot and run command cd ˜/Homestead && vagrant up
