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.

Tmux is a "terminal multiplexer", it enables a number of terminals to be accessed and controlled from a single terminal.
If you use Debian/Ubuntu, you can just run apt-get install tmux, and voila.
Since the title was about centos 7, then do the following step to install tmux.

$ tar xzvf libevent-2.0.21-stable.tar.gz
$ cd libevent-2.0.21-stable
$ ./configure && make
