When installing, I ran into a problem with "Fault Problem". I needed to turn off "Enable VT-x/AMD-V". There is no switch inside Virtualbox to turn this off, I needed to turn it off through XML.
To find the file, ~/VirtualBox\ VMs/Windows\ 3.11\*.vbox.
Then I had to find, "HardwareVirtEx" and turn all the flags to false.
- Also back the file up, just in case.
