Any example Vagrantfile to make 2 guests to communicate?

[zakiharis]

I saw issue #40 still open, but issue #30 is closed and said that I can use extra_qemu_args to achieve this.

But when I provisioned 2 guests, I cant make them ping each other.

Vagrantfile

Vagrant.configure('2') do |config|
  config.vm.box = "generic/ubuntu1804"

  (10..11).each_with_index do |address, index|
    vm_index = index + 1

    config.vm.define "nomad#{vm_index}" do |cp|
      cp.vm.hostname = "nomad#{vm_index}"
      cp.vm.provider "qemu" do |qe|
        qe.arch = "x86_64"
        qe.machine = "q35"
        qe.cpu = "max"
        qe.memory = "2G"
        qe.ssh_port = "50#{vm_index}22"
        qe.net_device = "virtio-net-pci"
        qe.extra_netdev_args = "net=10.100.100.0/24,dhcpstart=10.100.100.#{address}"
      end
    end
  end
end

Have you tried communicating over host port forward? Just portforward and use the gateway ip address for both machines on both sides

Could you provide example of config? (Default usage of vagrant port_forwarder ignored for qemu provider)

I have the same question about multiple configuration
