Hi all

Till this morning, I ran Windows 10 client on VirtualBox 6.1.24 on host Centos 8 stream kernel 4.18.0-315.el8 without problem (desktop).

I took the risk to do a "yum update" and as well as the kernel as the VirtualBox were updated: kernel going from 4.18.0-315.el8 to 4.18.0-326.el8 VirtualBox going from 6.1.24 to 6.1.26

But yum complained already :

... Installing: Package Arch Version Repository Size ================================================================================ VirtualBox-6.1 x86_64 6.1.26_145957_el8-1 virtualbox 86 M ...

Creating group 'vboxusers'. VM users must be member of that group!

Complete!

Vbox did not start my Windows 10 when I tried.

I also tried to install VirtualBox 6.0 and 5.2 with the same kind of error in yum.

I rebooted then the computer and started a previous kernel 4.18.0-310.el8 and reinstalled Virtualbox 6.1.26 now without those errors and it runs smooth as before. (Kernel 315 had the same vbox errors.)

However, when I went back to kernel 4.18.0-326 and tried starting there VirtualBox 6.1.26 again, he complained with :

... Failed to open a session for the virtual machine Windows10.

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. ...

(I tried that "/sbin/vboxconfig" but that tells me nonsense about registering because of EFI secure boot, but I did not change anything in the BIOS.)

or there is some conflict between the last kernels and VirtualBox?
