No vbox guest modules load in Debian guest after update VBox from v6 to v7

Post by PetyrVeliki »

After updated Virtualbox from v6 to v7 - I installed extension pack for v7 and then reinstalled guest additions for the guest.
The guest is Debian with kernel 4.9. I have also installed the headers for the kernel.

However - the resolution do not change when I resize the window. I saw that no `vboxdrv` exists and when I try to see the modules loaded - I get this:

Code: Select all

$ lsmod | grep vbox
vboxguest             256962  2
Any idea what could be wrong?

I decided to go with the variant to create a new VM and `scp` everything from the "broken" one. So I created the same VM - AntiX - and installed guest additions - and all worked as expected - I was able to change screen resolution.

However, I noticed that the kernel on the new VM is 5.10, while on the "broken" one was 4.9. So - I upgraded the kernel of the broken one - and voila! - I got the guest additions to work again :)
