Tip: keep Vagrant guest additions up to date

I found a handy plugin this weekend for keeping my PHP development Vagrant VM VirtualBox guest additions in sync: vagrant-vbguest

vagrant plugin install vagrant-vbguest

Every time you do a vagrant up it'll do a check, which might occasionally get annoying if you're in a hurry, so there's a config option to disable it on a per-vm basis:

# set auto_update to false, if you do NOT want to check the correct # additions version when booting this machine config.vbguest.auto_update = false
