How to update VirtualBox Guest Additions with vagrant
# Start the old vagrant
$ vagrant init centos-6.3
$ vagrant up
# You should see a message like:
# [default] The guest additions on this VM do not match the install version of
# VirtualBox! This may cause things such as forwarded ports, shared
# folders, and more to not work properly. If any of those things fail on
# this machine, please update the guest additions and repackage the
# box.
# Guest Additions Version: 4.1.18
# VirtualBox Version: 4.2.8
$ vagrant ssh
vagrantup:~$ sudo yum -y update
vagrantup:~$ cd /opt
vagrantup:~$ sudo wget -c \
-O VBoxGuestAdditions_4.2.8.iso
vagrantup:~$ sudo mount VBoxGuestAdditions_4.2.8.iso -o loop /mnt
vagrantup:~$ cd /mnt
vagrantup:~$ sudo sh --nox11
vagrantup:~$ cd /opt
vagrantup:~$ sudo rm *.iso
vagrantup:~$ sudo /etc/init.d/vboxadd setup
vagrantup:~$ sudo chkconfig --add vboxadd
vagrantup:~$ sudo chkconfig vboxadd on
vagrantup:~$ exit
# Now check that the Guest Additions work
$ vagrant halt
$ vagrant up
# Package the new VM
$ vagrant halt
$ vagrant package
$ mv

Thanks for the gist! One question: aren't line 22 and line 25 doing the same thing?

zbal commented Dec 5, 2013


Updated for Ubuntu 13.10 -- due to some bug that require VBox 4.3 and Ubuntu ships the vagrant box with 4.2.16

Thanks! This is exactly what I needed!

You might consider using the vbguest-plugin:

I think @epzee is right: line 25 (sudo /etc/init.d/vboxadd setup) doesn't seem necessary since the installer already removes the old kernel module and builds the new one.

Make sure you do this before you shut down: echo "ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA6NF8iallvQVp22WDkTkyrtvp9eWW6A8YVr+kz4TjGYe7gHzIw+niNltGEFHzD8+v1I2YJ6oXevct1YeS0o9HZyN1Q9qgCgzUFtdOKLv6IedplqoPkcmF0aYet2PkEDo3MlTBckFXPITAMzF8dJSIFo9D8HfdOV0IAdx4O7PtixWKn5y2hMNG0zQPyUecp4pzC6kivAIhyfHilFR61RGL+GPXQ2MWZWFYbAGjyiYJnAmCP3NOTd0jMZEnDkbUvxhMmBYSdETk1rRgm+R4LOzFUGaHqHDLKLX+FIPKcF96hrucXzcWyLbIbEgE98OHlnVYCzRdK8jlqm8tehUc9c9WhQ== vagrant insecure public key" > .ssh/authorized_keys

Perfect :)

This does not seem to work for me, perhaps I am doing it wrong. I used a basebox (precise32), then uninstalled the guest additions, installed the kernel headers, dkms, etc, and latest guest additions (5.0.10). I then ran the guest additions. After exiting and halting, I did a vagrant package. When I deploy this new .box (vagrant box add, vagrant init, vagrant up).. it has the OLD guest additions it seems every time. Is there something special needed to make the modified additions stick in a 'package'?

@krutcha this guide is for CentOS, not Ubuntu.

Thanks for that tip.It worked like charm!
Saved me many hours of investigation.

Hi guys, I'm sorry I'm pretty late to this party.

I have two apparent issues with Vagrant: the guest additions not matching and the NFS mount error. When I run Vagrant Up/Reload I get this...

I have been having trouble for a few days. Do you think these isses could be related?



I just ran 'vagrant ssh', 'apt-get update', and 'apt-get install nfs-common nfs-kernel-server'.

Ran like a dream.

Sorry to bother you, cheers.

"sudo /etc/init.d/vboxadd setup" : "command not found".
