Hi All,

Step 3: Before starting Multibeast, you have to go the 'Security' section of System Preferences in Mac OS X, go to the 'General' section, and check 'Anywhere' in the 'Allow applications' section. Once that's done, run Multibeast and install the following options. Download Required File to Install macOS Big Sur on VirtualBox on Windows PC.

While it will be macOS 11 (it was released as a developer beta as 10.16), macOS Big Sur seems to have some Kernel extension changes that i think will require Virtualbox fixes. Here is the error I get trying to launch my Ubuntu VM on 6.1.10.
Failed to open a session for the virtual machine Ubuntu Server.
The virtual machine 'Ubuntu Server' has terminated unexpectedly during startup with exit code 1 (0x1).

From the macOS 11 Big Sur Release Notes:

Virtualbox Macos Big Sur Kernel Driver Not Installed

Kernel
New Features
The kern.argmax limit has been increased, allowing programs to receive longer argument lists. (48661669)
Darwin kevent now allows non-parent processes to register for NOTE_EXITSTATUS, which delivers the same values as the wait() family of functions in the event data. Refer to the wait4() man page for more information. This event is subject to the following security checks:
The requesting process is allowed to send signals by sandbox restrictions.
The requesting process and the target process are running as the same user or the requesting process has root privileges. (58134463)
Known Issues
Installing a new kernel extension requires signing in as an Admin user. During kernel extension development, every time a kernel extension is changed, it must be signed and notarized. In both cases, your Mac must be restarted to load the extension. (55068348)
Remote panic dumps aren't currently available. (57915324)
New in macOS Big Sur 11 beta, the system ships with a built-in dynamic linker cache of all system-provided libraries. As part of this change, copies of dynamic libraries are no longer present on the filesystem. Code that attempts to check for dynamic library presence by looking for a file at a path or enumerating a directory will fail. Instead, check for library presence by attempting to dlopen() the path, which will correctly check for the library in the cache. (62986286)
kmutil install might fail to build a development kextcache. (63772702)
Workaround: Copy the release .elides to the locations of the development .elides:
sudo cp /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.development.elides
sudo cp /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.kasan.elides
sudo cp /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/BootKernelExtensions.kc.debug.elides
sudo cp /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.development.elides
sudo cp /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.kasan.elides
sudo cp /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.elides /path/to/livemount/System/Library/KernelCollections/SystemKernelExtensions.kc.debug.elides
Use only absolute paths with the --volume-root option of kmutil, and don't use a trailing /. (63773848)
After removing a DriverKit extension, restart your Mac to complete uninstallation. (63995046)
Adhoc signed kernel extensions are displayed with a developer name of unknown in update dialogs and in Security preferences. (64215260)
Symbols exported by both xnu and Apple kernel extensions will change. Recompile your kernel extension with each update to macOS Big Sur 11 beta to ensure compatibility. (64262563)
Moving a kernel extension bundle out of /Library/Extensions might not completely uninstall it. (64331929)
Workaround:
Remove the extension from /Library/Extensions.
Boot to macOS Recovery.
Run Terminal.
Enter the command kmutil invoke-panic-medic.
Restart your Mac.
Follow the prompt to open System Preferences and navigate to Security & Privacy.
Follow the prompt to restart.
An unexpected System Extension Updated alert for third-party kernel extensions which are included in macOS might appear. These include: Accusys, Inc., ATTO Technology, Inc., Areca Technology Corporation, CalDigit, Inc., HighPoint Technologies, Inc., Promise Technology Mobile Apps, and Other World Computing. (64337113)
Deprecations
Kernel extensions using certain deprecated KPIs no longer load. Refer to the support page . While macOS Big Sur remains in development, you can temporarily disable System Integrity Protection to allow these deprecated extensions to load. (55068348)
