I’m running Rocky 8.5 and trying to install the guest addons from VirtualBox 6.0.10. I’ve installed the packages to build but the log says that it’s missing files.

No one has had success fixing this issue loading VirtualBox Guest Additions on Rocky 8.9? ---

Have you got the `kernel-devel` package installed? Since that is the package that has that autoconf.h file. ---

Good afternoon, Ian. Yes, kernel-devel is installed and autoconf.h is in /usr/src/kernels/(current\_kernel)/include/generated/autoconf.h. Installing kernel-devel is one of the early things I did when I installed the package in VirtualBox. Eric ---

> [@ericp-nh](#): > > Do any of you actually have a running VB Guest Additions on a Rocky 8 guest, even if it Just Worked right out of the box? I’m beginning to wonder if there is something basic missing in the Rocky distro. Sadly I don’t personally. Since the kernel includes the KVM module, I’ve been using this for VM’s for years now and using virt-manager as the GUI interface for managing them. Although you can do it with cockpit as well via web browser. I tend to stay away from Oracle VirtualBox because it’s always been problematic in one way or another. I’m sure there are others here that do use it though that might be able to help out. ---

I’m running rl9 in a VBox-7.0.12 vm on a fedora host. I just built the Guestaddition modules and installed them today. The steps I took were to install the prerequisite software: make gcc kernel-devel dkms I then loaded the vbox guestadditions iso in the vbox device manager for the rl9 vdi. As root I used parted to find that the virt cdrom is /dev/sr0. I created /mnt/iso to mount the iso there then cd’d to that directory. I ran the command: sh ./VBoxGuestAdditionsLinux.run The build completed successfully. I post this response only as an example of the steps I took. I understand you are using rl8 and the long time service “6.1” version of vbox. Does you guestadditions version match the host VirtaulBox version? ---

Thanks, jbkt23. I ended up doing most of what you describe. I had earlier tried to install Rocky 9 and got kernel crashes during the installation process, which is why I reverted to Rocky 8. I upgraded VirtualBox to 7.0.14 and was then able to install Rocky 9. Added all the required packages like dkms, kernel-devel, etc. and the Guest Additions then installed correctly. So, the answer is that (1) Rocky 9 apparently won’t install on VB6, it requires VB7; and (2) Guest Additions works on Rocky 9 but (so far) not on Rocky 8. So, I’m all set for now. Thanks to everyone for your help. Eric ---
