Virtualbox VM GUI remains black

[aristosvo]

I've played a bit around with Packer and Virtualbox, but while vagrant ssh works as expected, the GUI remains black.

My Vagrantfile looks like this

Vagrant.configure("2") do |config|
  config.vm.box = "centos7-desktop"
  config.vm.box_version = "0"
  config.vm.hostname = "centos-dev"
  config.vm.synced_folder '.', '/vagrant', type: :virtualbox

  config.vm.provider :virtualbox do |vb|
    vb.name = "centos-dev"
    vb.gui = true
    vb.cpus = 2
    vb.memory = 4096
  end

  #config.vm.provision "shell", inline: <<-SHELL
  # sudo yum -y groupinstall "GNOME Desktop"
  # sudo systemctl set-default graphical.target
  # sudo systemctl start graphical.target
  #SHELL
end

I am experiencing this as well, seems to be when centos was upgraded to 7.5. Interestingly while packer is building the GUI works fine, it's when I vagrant up with a new build there is an issue.

UPDATE: I updated virtualbox to the latest version (5.2.18 at the time of writing) and this seems to have resolved the issue
