How do I increase the RAM and set up host-only networking in Vagrant?

Question

I would like to increase the RAM to at least 1 GB and I would like to configure “Host-Only” networking to use \"199.188.44.20\".

This is my Vagrantfile:

Answer 1

I could not get any of these answers to work. Here's what I ended up putting at the very top of my Vagrantfile, before the Vagrant::Config.run do block:

Vagrant.configure("2") do |config|
  config.vm.provider "virtualbox" do |vb|
    vb.customize ["modifyvm", :id, "--memory", "1024"]
  end
end

I noticed that the shortcut accessor style, "vb.memory = 1024", didn't seem to work.
