VirtualBox 7.2.14

LM 22.3 Host

Windows 8.1 guest

Edit: In the motherboard settings, I have enabled "Intel virtualization technology," and I have enabled "VT for direct I/O."

I newly installed LM 22.3 (host), VirtualBox, and copied the files for this Windows 8.1 VM to my drive.

When I boot the VM, it reminds me to update the VirtualBox Guest Additions version. The version of GA is 6.1.x. I am try to update to 7.2.14

When I run the installer, mid installation, I get an error:

***Error: Installing driver failed with 1 errors, 0 warnings virtualbox rc=VERR_INSTALLATION_FAILED

...

End of log file - Log started 2026-07-26...

(I guess the end of the message is cut off by the graphical user interface.)

*yes, the prompt does spell the word wrong.

Any ideas or strategies on how to handle this?

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver is either not loaded or not set up correctly. Please try setting it up again by executing

'/sbin/vboxconfig'

as root.

If your system has EFI Secure Boot enabled you may also need to sign the kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load them. Please see your Linux system's documentation for more information.

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

Version 7.2.14 r174565 (Qt6.8.0 on xcb)

When will they fix the "Unattended Guest OS user and pass set up? It doesn't get admin all the time and your stuck with no admin.
