Just a friendly reminder; you remember the requirements in the new ticket page? They're actually listed before the ticket form, so I'm not sure how you missed it. I don't see any of them fulfilled, not even a VBox.log (the VBoxSVC.log is not required at this point)...

Attach a (full) log file ("Machine" menu/"Show Log" in the main VirtualBox Manager window) straight away to save time for you and for us. The log file contains a lot of useful information about both the host and the guest systems as well as information about what happened during a particular machine run. Please do not cut and paste it.

May I also suggest something? It's usually better and faster, if issues get first addressed in the ​VirtualBox forums. More than 95% of the issues are resolved over there, which keeps the developers focusing on the bug fixes and enhancements, and there is no need for another ticket to keep track of. Plus there are a lot more eyes in the forums.

So, if you can, please open a new thread in the ​Linux Guests section of the forums. Please be sure to mention that you came from the bug tracker and include the ticket number.

According to a ​message by the OP in the forums, the problem was the unavailability of VT-x from the BIOS setting.

The issue has been resolved, the ticket can be closed.
