Then uninstall and re-install virtualbox. If needed go to System Preferences - Privacy - General and accept the extensions. If someone needs to reset kext completely: 1 Boot into recovery and delete entries in kext database with sqlite3 commands. (Disable Firmware Password before - if set) 3 Uninstall and re-install virtualbox. Big Sur will completely disallow most 3rd party kexts. The issue is that Virtualbox heavily relies on its kexts for core functionality. I see no fast way for them to work around this as the only option is to use userland MacOS APIs - e.g. Vmnet for virtual networks and hypervisor.framework for virtualization. – pinkeen Sep 2 '20 at 6:27.

Since macOS Catalina users haven’t been able to run 32-bit apps anymore. While many apps’ creators developed new, 64-bit versions of the apps by now, there are still some applications and plugins that can only run on 32-bit Macs. If you need to run a 32-bit app on Big Sur, you can do it with the help of a virtual machine.
Virtual machines allow you to install and open an earlier version of macOS (for example Mojave) in a window on your Mac Big Sur or Catalina. You will be able to run two operating systems at the same time, which is handy if you want to open a single 32-bit app alongside your 64-bit Mac applications. However, when you run a virtual machine, your computer’s resources are split between the two operating systems, so everything may run slower than usual.
Popular virtualization apps for macOS are Parallels Desktop, VMware Fusion and VirtualBox. This article will cover pros and cons of using VMware Fusion, VirtualBox and Parallels.
Install 32-bit apps on macOS Big Sur With Parallels Desktop
Parallels Desktop is very intuitive and easy-to-use for regular computer users. You can open another operating system in a separate window (including a full screen mode), or you can turn on Coherence mode. In Coherence mode the virtual machine will run in the background, while 32-bit programs can run alongside your regular Mac apps. Parallels Desktop allows you to copy and paste or drag and drop between both OS’s without any problems.
Parallels Desktop prices start at $79.99, however there is a free trial period available.

Install Os X On Virtualbox
VMware Fusion is another popular virtualization software for Macbooks. It is close to Parallels in terms of functionality and pricing, but VMware’s Fusion supports a larger number of operating systems than Parallels. On the other hand, Parallels is easier for beginners, and runs a little smoother. Otherwise, these two programs are approximately on the same level.
VMware Fusion offers a free trial period to its users, same as Parallels, so you may try both for free and decide which one you like better, before committing.
Install 32-bit apps a Mac Big Sur Via VirtualBox
If you don’t plan to spend extra money on virtualization software, there’s always VirtualBox by Oracle. VirtualBox is a pretty decent free alternative to paid software if not slower, less polished and missing some handy functions. If you need to run some resource intensive apps on a virtual machine, VirtualBox might not be the best choice for you. VirtualBox also requires more technical knowledge than, for example, Parallels, as users need to tune some settings themselves when installing it. However, if you are a power user already or don’t mind doing a little more work, and you are not going to run resource intensive software, VirtualBox is a good (and free!) alternative.
