Unfortunately, dkms attempts to rebuild all guest kernel modules including vboxvideo during every reboot. This adds a serious delay for each reboot and failure messages in the logs. The system should simply ignore vboxvideo if X is not installed. Actual result: dkms rebuilds additions on every guest reboot Expected result: dkms rebuilds additions only when kernel changes Additional details on test system: VirtualBox 4.3.4 Host Fedora 19 x86_64 Guest CentOS 6.5 both i386 and x86_64 To reproduce exactly: Install a CentOS 6.5 using the minimal selection Do not update yet Install gc bzip2 and kernel-devel for installed kernel. Mount guest additions mount /dev/sr0 /mnt Install guest additions cd /mnt; ./VBoxLinuxAdditions.run reboot update operating system to get latest kernel reboot Work Around: Add a check to /opt/VBoxGuestAdditions-4.3.2/src/vboxguest-4.3.2/Makefile to ignore vboxvideo if the X command is not installed. Comment out the three vboxvideo related lines in /opt/VBoxGuestAdditions-4.3.2/src/vboxguest-4.3.2/dkms.conf There is probably a better way. This worked for me.
