Comment 4 for bug 1553666

i am simply using "vagrant up" command, and my Vagranfile is:

# -*- mode: ruby -*-

# vi: set ft=ruby :

ENV['VAGRANT_DEFAULT_PROVIDER'] = 'libvirt'
VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  config.vm.box = "ubuntuserver64"

  # Turn off shared folders
  config.vm.synced_folder ".", "/vagrant", id: "vagrant-root", disabled: true

  config.vm.define "deploy" do |deploy_config|
    deploy_config.vm.hostname = "deploy"

    deploy_config.vm.provider "libvirt" do |v|
        v.memory = 2048
        v.cpus = 2
        v.nested = true
        v.volume_cache = 'none'
    end

  end
end
