Fetch and run CentOS7 minimal

Other boxes can be fetched at http://www.vagrantbox.es/

mkdir vagrant; cd vagrant
vagrant box add centos7 https://github.com/holms/vagrant-centos7-box/releases/download/7.1.1503.001/CentOS-7.1.1503-x86_64-netboot.box
vagrant init centos7
vagrant up
vagrant ssh

Upgrade the memory and cpu

Edit the Vagrant file with the following

config.vm.provider "virtualbox" do |vb|
  # Display the VirtualBox GUI when booting the machine
  # vb.gui = true
  # Customize the amount of memory on the VM:
  vb.memory = "2048"
  # Change the number of CPUs
  vb.cpus = 2
end

Customise the CentOS to let remote ssh login

config.vm.network :forwarded_port, guest: 22, host: 22222, host_ip: "0.0.0.0", id: "ssh", auto_correct: true

Now you can connect using ssh -p 22222 vagrant@<ip address of host> (default password: vagrant)
