Apparently, there was a long discussion since Big Sur beta was released. Fortunately, there was a solution tested and posted by NickyD at the bottom of the thread.

Tested by NickyD: VirtualBox 6.1.16 r140961 running on BigSur macOS 11.0.1 (20B29) / Darwin 20.1.0

Tested by me: Virtualbox Offical release 6.1.16 ( r140961 (Qt5.6.3)) + BigSur MacOS11.0.1 (first public release of Big Sur), It worked well for me, too.

Info about Virtualbox kernel modules: https://www.virtualbox.org/manual/UserManual.html#externalkernelmodules

• VBoxDrv: VirtualBox Linux kernel driver
• VBoxNetFlt and VBoxNetAdp: network driver
• VBoxUSB: USB support

I was not familiar with kextload, so I summarize some info collected from https://osxdaily.com/2015/06/24/load-unload-kernel-extensions-mac-os-x/

kext is Kernel extensions for short, which are modules of code that are loaded directly into the kernel space of Mac OS X, able to run at a low-level to perform a variety of tasks. Most kexts are part of the core Mac OS X system software, typically hardware device drivers, but some third party apps will install a kext as well.

kextload: cmd to load a kernel extension into Mac OS X.

sudo kextload /path/to/kext.kext

kextload -b: use the bundle identifier (which are frequently the targets of defaults commands)

sudo kextload -b com.apple.driver.ExampleBundle

Either way, hit return and with the entry of the administrator password the kernel extension will be loaded into Mac OS X.

kextstat: list the kernels loaded

$ kextstat |grep com.apple.driver.ExampleBundle
125 0 0xdddddd7f23351040 0x5000 0x5000 com.apple.driver.ExampleBundle (1) 12 8 7 5 4 2 1

kextunload: unload a kernal extension.

Virtualbox Macos 10.15

sudo kextunload -b com.apple.driver.ExampleBundle

Or by pointing directly to the kernel extensions path:

Macos 11 Big Sur Virtualbox

sudo kextunload /System/Library/Extensions/ThirdPartyMystery.kext
