Guest Additions not working on Centos 9 Stream since RHEL 9.4 release

[chris-llu]

The install of Guest Additions started to fail on Centos 9 Stream starting with the kernel released with RHEL 9.4 (5.14.0-427). Centos 9, which I use as a guest on my Windows host has the same kernel version as RHEL 9.

I tested this version an later versions of the kernel and the install does not work. There is a compilation error in the log file. Please see attached. It looks like when make is pointed at the /lib/modules/5.14.0-460.el9.x86_64/build directory, it cannot find either include/generated/autoconf.h or include/config/auto.conf. But it is there in /usr/src/kernels/5.14.0-460.el9.x86_64/include/config/auto.conf. Please remember that /lib/modules/5.14.0-460.el9.x86_64/build is sys linked to /usr/src/kernels/5.14.0-460.el9.x86_64.

There are a few people in the forums that have reported this issue. It is host-agnostic and is probably just an issue with the Guest Additions install script.

Worked for me as well - thanks @sergiomb!

The solution from @sergiomb works for some things like mouse and keyboard integration, but I am still not able to use shared folders as I previously could.

Is anyone else still having an issue with shared folders after following the solution from @sergiomb?

@jag-yw we need more information , with Centos-stream 9 as guest I have shared folder working

For me also this does not really work. I mean, it installs but i get all kind of graphics glitches and e.g. copy and paste/clipboard between guest and host does not work.

I am also maybe not a pro user. Can someone share some details on the suggest fix using the guest additions installed via the package manager? Is this the intended approach or still experimental. At least on the link it says "keep in mind this still in a very early stage". Is there any way to get the guest additions installed via the "old" approach. I.e. mounting guest additions from drive adn running VBoxLinuxAdditions.run?

Can you check this ​https://pointieststick.com/2024/03/08/psa-enable-3d-acceleration-in-your-virtualbox-vms/ ?

Seems that "For KDE Plasma, you need to enable 3D acceleration (which is not on by default)."

you can't install both guest additions, to install Centos Stream 9 guest additions you should remove Oracle guest additions first, navigate to /run/media/<my user name>/VBoxGAs_x.x.x issue command './VBoxLinuxAdditions.run uninstall'

Other thing is when you want run VirtualBox on Centos Stream 9 as server, that is for what patch propose for, because guest drives are all available in official kernel (kernel.org)

Fixed with VirtualBox 7.0.20.

Hello, I can confirm that VirtualBox 7.0.18 was not working on CentOS host with kernel later than 5.14.0-446.el9.x86_64. It's now working perfectly with Virtualbox 7.0.20 on CentOS host with kernel 5.14.0-479.el9.x86_64. Thank you for this patch.
