This has been happening recently, but we're not sure what's causing it yet. Please see if this helps: viewtopic.php?f=6&t=106043

I was able to solve this problem by adding an additional CPU core for a total of 2. I also maxed out the video ram (128 mb) so that VirtualBox stopped displaying an error.

WOW man thank yoiu, I added 2 core and 128 mb like you, now is working!
But is still have one problem, that when i turn on my ubunty under the vm I get black screen sometimes...
But rebooting the vm 3 or 4 times solves that

Glad the advice worked!

Ubuntu is known to go blackscreen if there is not enough free disk space to start the desktop environment. This happens in real PCs too. The solution is to log on text-only and delete stuff until the desktop environment can start. Web-search how to fix this in an Ubuntu PC and apply the steps to the VM. Also see How to Resize a Drive

The screenshot shows the virtual disk file now capable of going up to 20GB, good. The intent of checking the free space in the disk was to check how much Ubuntu could see. It is still possible that Ubuntu cannot make use of the free space, unless you also expanded the partition inside Ubuntu. Did you do that too? (The "resizing" tutorial also mentioned this partition resizing as a necessary step.)

Start the VM from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the VM from within the VM's OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Right-click the VM in the main Virtualbox window's VM list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.
