ssh - Vagrant stuck connection timeout retrying

Question

My vagrant was working perfectly fine last night. I've just turned the PC on, hit vagrant up, and this is what I get:

==> default: Clearing any previously set network interfaces...
==> default: Preparing network interfaces based on configuration...
    default: Adapter 1: nat
    default: Adapter 2: hostonly
==> default: Forwarding ports...
    default: 22 => 2222 (adapter 1)
==> default: Booting VM...
==> default: Waiting for machine to boot. This may take a few minutes...
    default: SSH address: 127.0.0.1:2222
    default: SSH username: vagrant
    default: SSH auth method: private key
    default: Error: Connection timeout. Retrying...
    default: Error: Connection timeout. Retrying...
    default: Error: Connection timeout. Retrying...
    default: Error: Connection timeout. Retrying...
    default: Error: Connection timeout. Retrying...
    default: Error: Connection timeout. Retrying...
    default: Error: Connection timeout. Retrying...
    default: Error: Connection timeout. Retrying...
    default: Error: Connection timeout. Retrying...
    default: Error: Connection timeout. Retrying...
    default: Error: Connection timeout. Retrying...
    default: Error: Connection timeout. Retrying...
    default: Error: Connection timeout. Retrying...

Has anyone had this before? vagrant isn't widely covered on the web yet and I can't find a reason why this is occurring.

Answer 1

I solved this problem, and will answer in case anyone else has a similar issue.

What I did was: I enabled the GUI of Virtual box to see that it was waiting for input on startup to select whether I wanted to boot directly to ubuntu or safemode etc.

To turn on the GUI you have to put this in your vagrant config Vagrantfile:

config.vm.provider :virtualbox do |vb|
  vb.gui = true
end
