Fairly new to Vagrant, so bear with me if I don't understand the process.

I downloaded a CentOS box off http://www.vagrantbox.es/

Started it up running VirtualBox 4.2.4 and got this message:

[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: 4.0.8

VirtualBox Version: 4.2.4

So I used the vbguest plugin to update the guest additions, then repackaged the box as suggested. Having replaced the old box and loading it up I get the same message about guest additions being outdated, but vbguest reports that they are up to date (the automatic vbguest update is disabled in my Vagrantfile):

Vagrant::Config.run do |config|    
    config.vm.box = "centos56_64"

    config.vbguest.auto_update = false
    config.vbguest.no_remote = true
end

And the commands:

dtest$ vagrant up
[default] Importing base box 'centos56_64'...
[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.

Since they appear to be updated after an install, I could ignore the message. But is it possible to get rid of it?
