If you want to package an existing vm to use it later as a clone, just run

# vagrant package

This will build a “.box” file of your vm, which you could put in a webserver to use it whenever you need to create another vagrant vm.

If you want to use the virtualbox console for your vagrant vms, you need to enable that feature in the “Vagrantfile” settings file, just add these lines

config.vm.provider "virtualbox" do |v|
        v.customize ["modifyvm", :id, "--vrde","on"]
        v.customize ["modifyvm", :id, "--vrdeport","3389-4000"]
end

install virtualbox and vagrant first, then create a working directory

# mkdir /opt/vagrant
# cd /opt/vagrant/

Initialize the environment in the directory, in this case we’ll download a ubuntu precise vm

# vagrant box add precise32 http://files.vagrantup.com/precise32.box
# vagrant box list

Edit Vagrantfile and make sure the vm points to “precise32” instead of “base”:

  config.vm.box = "precise32"

Start the vm

# vagrant init
# vagrant up

Connect to the vm

# vagrant ssh

Additional…
for a centos6.5 you can find a vm here:

# vagrant box add centos65 http://opscode-vm-bento.s3.amazonaws.com/vagrant/virtualbox/opscode_centos-6.5-i386_chef-provisionerless.box

Install it in the master node

# apt-get install ansible

add a section to /etc/ansible/hosts

[slaves]
d510
d610

Ping them (make sure you have ssh keys setup in authorized_keys)

# ansible -m ping -u root all
d510 | success >> {
    "changed": false,
    "ping": "pong"
}

d610 | success >> {
    "changed": false,
    "ping": "pong"
}

Make sure you have the latest java from oracle

# java -version
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

Make a diretory for the server
# mkdir /opt/minecraft

Download minecraft jar
# cd /opt/minecraft && wget https://s3.amazonaws.com/Minecraft.Download/versions/1.8.1/minecraft_server.1.8.1.jar

Run the server for the first time, it will create its settings file and ask you to accept the eula
# java -Xms32M -Xmx512M -jar /opt/minecraft/minecraft_server.1.8.1.jar nogui

Quit by issuing ctrl-c and then edit eula.txt,set eula=true

Set your admin user in ops.json
[

Install a module

# puppet module install AlexCline-fstab

Make sure all nodes have ntp and are in sync:

# ntpq -pn

Install packages in the puppet server:

# apt-get install facter puppet puppetmaster

Install packages in the puppet clients:

# apt-get install facter puppet

Stop and start puppet in puppet server:

# service puppetmaster stop && service puppetmaster start && service puppetmaster status

Add server section in each puppet client /etc/puppet/puppet.conf:

[main]
logdir=/var/log/puppet
vardir=/var/lib/puppet
ssldir=/var/lib/puppet/ssl
rundir=/var/run/puppet
factpath=$vardir/lib/facter
prerun_command=/etc/puppet/etckeeper-commit-pre
postrun_command=/etc/puppet/etckeeper-commit-post
certificate_revocation = false
[agent]
server = aspireone

List and sign the client cert requests in the puppet master server:

# puppet cert list && puppet cert sign d510.lan && puppet cert sign d610.lan

In case the certs get messed up… in the master server:

 # puppet cert sign -all && puppet cert clean --all 

And in the agent servers:

 # rm -rf /var/lib/puppet/ssl/* && puppet agent --no-daemonize --server aspireone --onetime --verbose && puppet agent --test
