Ubuntu 16.04 does not start on VB 5.2.12.22591

[LSFDash]

Hello. I've received the following message while trying to host Linux Ubuntu 16.04 (32-bit) on VirtualBox 5.2.12.22591.
"A critical error has occurred while running the virtual machine and the machine execution has been stopped."
As a newbie to VirtualBox, I do not know how to read the log file for errors. Will someone please assist on identifying the problem and provide guidance towards a possible solution?

Thank you!

Normally I'd say that your CPU can/can't use VT-x. But your E7500 CPU has an indication that I honestly haven't seen before: "See Ordering Info".

So, I don't know if your CPU supports VT-x or not. You'd have to download one or more CPU identification programs (preferably from Intel) and find out what the capabilities of your CPU are. And then adjust your BIOS accordingly, if possible.

BTW, I didn't see a Guru Meditation in your log. Did you "truncate" it by any chance?

I saw this processor once before and found the following on Tom's Hardware:

First of a little information, if Intel® Core™ 2 Duo E7500 processor that you have has a sSpec# of SLGTE or SLB9Z then it doesn’t have VT-x support. On the other hand if it is SLGTE then the processor will VT-x support. The SLGTE was the only one of the E7500’s that were offered as a boxed product (retail package).

It then becomes a bit recursive as it sends you back to the information on the Intel Ark page that you linked to earlier.

The fact that the error message is "VT-x is disabled in the BIOS" rather than "VT-x is not available" leads me to believe that VirtualBox has already looked at the capability flags, and the processor supports VT-x.

So, go into the host BIOS and enable it. Tips can be found in FAQ: I have a 64bit host, but can't install 64bit guests.
