I installed VirtualBox on Windows. I set it up to boot Ubuntu14. I enabled the virtualization option for the CPU to enabled (before that, the VM would not boot up complaining about i686 CPU). I rebooted the OS. After this, when I try starting the VM, it gives the following error:
The VM session was closed before any attempt to power it on.
Result Code:
E_FAIL (0x80004005)
Component:
SessionMachine
Interface:
ISession {7844aa05-b02e-4cdd-a04f-ade4a762e6b7}
What did I do wrong and how can I fix it? Thanks. I did not post on serverfault since this is not a server but a laptop.

If you're encountering freezing, this is one of the first things to try turning off. In the menu on the left in VirtualBox, right-click on the Ubuntu virtual machine you're having problems with, then select Settings. Here, click the Display tab and make sure that “Enable 3D Acceleration” is not selected.
Verify sufficient disk space for proper virtual machine operation. One of the most common causes for a virtual machine to become unresponsive is that the hard drive has run out of space. Without sufficient space for logging and IO, the virtual machine may be unable to continue to function.
discarding the "saved state" of the virtual machine using the virtual box GUI allowed me to launch the Ubuntu VM.

Just right click and choose "clear saved state" to restart or click on the orange discard icon.
