title: Increase memory of a particular vagrant box
body: <p>I have this Vagrantfile. Here I defined the memory to be 2048 for all VMs. But I want my puppet master to have 4096 and agents to have 2048. How to do that?</p>
  
  <pre><code>Vagrant.configure("2") do |config|
    config.vm.synced_folder ".", "/vagrant", type: "virtualbox"
  
    config.vm.provider "virtualbox" do |v|
      v.memory = 2048
      v.cpus = 2
    end
  
    config.vm.define "puppetmaster" do |pm|
      pm.vm.box = "centos/7"
      pm.vm.network "private_network", ip: "192.168.33.10"
      pm.vm.hostname = "puppetmaster"
    end
  
    config.vm.define "puppet-agent-centos" do |pac|
      pac.vm.box = "centos/7"
      pac.vm.network "private_network", ip: "192.168.33.11"
      pac.vm.hostname = "centos-agent"
    end
  
    config.vm.define "puppet-agent-ubuntu" do |pau|
      pau.vm.box = "ubuntu/xenial64"
      pau.vm.network "private_network", ip: "192.168.33.12"
      pau.vm.hostname = "ubuntu-agent"
    end
  end
  </code></pre>
  
  <p>Thanks!</p>
