Multi-machine Vagrantfile for VirtualBox or VMware Fusion

The following Vagrantfile shows the syntax for setting up multiple virtual machines using VirtualBox or VMware Fusion.

In addition, the example shows the syntax for globally turning off:

• shared folders
• setting each virtual machine’s hostname
• setting each virtual machine’s CPU
• setting each virtual machine’s memory
• adding a private NIC on the 192.168.205.0/24 network.

I have also put together a multi-machine Vagrantfile with shorter, cleaner syntax using JSON and loops.

Example Vagrantfile

    override.vm.box = "base"
