Vagrant up fails

[funroll]

Getting errors trying to bring the machine up:

dev-mini:sandboxed-opengrok DEV$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Clearing any previously set forwarded ports...
==> default: Clearing any previously set network interfaces...
==> default: Preparing network interfaces based on configuration...
default: Adapter 1: nat
==> default: Forwarding ports...
default: 8080 => 8080 (adapter 1)
default: 22 => 2222 (adapter 1)
==> default: Booting VM...
==> default: Waiting for machine to boot. This may take a few minutes...
The guest machine entered an invalid state while waiting for it
to boot. Valid states are 'starting, running'. The machine is in the
'poweroff' state. Please verify everything is configured
properly and try again.

If the provider you're using has a GUI that comes with it,
it is often helpful to open that and watch the machine, since the
GUI often has more helpful error messages than Vagrant can retrieve.
For example, if you're using VirtualBox, run vagrant up while the
VirtualBox GUI is open.
dev-mini:sandboxed-opengrok DEV$

Then I tried from VirtualBox and got this:

Failed to open a session for the virtual machine sandboxed-opengrok_default_1401483828771_91439.

The virtual machine 'sandboxed-opengrok_default_1401483828771_91439' has terminated unexpectedly during startup with exit code 1.
