20684	VM won't start after reboot on MacOS host	Paul W Panish		"After reboot on MacOS Monterey VM won't load giving following error message:

'''Kernel driver not installed (rc=-1908)'''

'''Make sure the kernel module has been loaded successfully.'''

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

After reinstall everything works properly including guest shutdown and restart until reboot of the host, after which the above repeats itself.

Trying to attach log file, first time I've file a bug report here and process is not clear. Nothing happens when I check 'have files to attach'. There are errors at startup about firmware versions, however I don't know if this simpley refers to the driver not being loaded, or if there is actually a firmware incompatibility.

Tried installing latest interim build (VirtualBox-6.1.29-148369-OSX.dmg). Disabled System Integrity Protection as instructed, however the build would not verify as installable on this system."	defect	closed	other	VirtualBox 6.1.28	duplicate			Linux	Mac OS X
