I have Fedora 11 on a VirtualBox. I installed the Guest Additions package following these instructions:

It works fine, until I do a System > Administration > Software Update. After the reboot, the guest additions don't work anymore (the resolution is not nice, the cursor does not automatically follows, the shared folders won't work, ...).

I have to re-do the guest addition install every time I do an update (and reboot).

Is that normal? What Can I do?

Are you using a live CD or a full install on VirtualBox ? – Sathya Nov 13 '09 at 0:30

You can try installing (via YUM) the dynamic kernel module support package, which should automatically rebuild your kernel modules. If that doesn't work, you'll need to re-install the VBox guest additions whenever you update the kernel.

If I remember correctly the Guest Additions build several modules during their installation (e.g. the shared folder module). Modules are tight to the Kernel version you're running (e.g. 2.6.31) so whenever this changes you have to install the Guest Additions again.

Answering your question it is normal if the Kernel version was updated, you won't have to do it whenever you update your system, just when the Kernel gets updated.
