What happened?

You can install the VirtualBox Guest Additions by running VBoxLinuxAdditions-arm64.run.
When you try to run them e.g. as VBoxClient --vmsvga, however, it will output two error messages about missing libraries, it does not find libX11.so nor libwayland-client.so.

To actually run the guest additions, you have to create two symbolic links in /usr/lib64: link libX11.so.x.y to libX11.so and libwayland-client.so.x.y.z to libwayland-client.so (use the real number for x, y, z, e.g. what ls -l shows you).

This happens with all Linux distros that I tested: openSUSE MicroOS, openSUSE Tumbleweed, AlmaLinux 9

How can we reproduce this?

• Install VirtualBox 7.2.0 on ARM Windows machine, e.g. a Surface Pro Snapdragon X Pro
• Install e.g. a AlmaLinux 9 (arm) guest os
• Install the kernel headers (package kernel-headers on AlmaLinux, kernel-sources on openSUSE)
• Insert the virtual guest additions CD image
• Run VBoxLinuxAdditions-arm64.run, make sure it shows no error message
• Run VBoxClient --vmsvga
• Look at the commands output
