Critical Error booting a VDI with ubuntu variant

[ppl]

Is anyone familiar with the message:

A critical error has occurred while running the virtual machine and the machine execution has been stopped.
For help, please see the Community section on

I installed an ubuntu variant onto a virtual drive and was busy for the last week and when I tried booting it up today I get the above message. I have attached the log file.

Someone mentioned in another post about checking if drive virtualization was enabled in the bios and it is enabled.

Any help would be great.
Thanks

You have the following in your log:

For Guru Meditation errors, you should head to the bugtracker and either search for an appropriate bug where you'll attach your logs and other vital information, or open a new bug report.
