Toshiba P50 hardware virtualization issues

This is to hopefully help anyone that purchases a Toshiba P50 laptop. I purchased it with an Intel i7 4700MQ, specifically because it was one of the cheapest i7s with VT-x support. I work with VMs a lot. So in the BIOS, under Advanced, there's a Virtualtization Technology setting. The only options are "Disabled" and "VT-x Only".

I obviously chose VT-x Only thinking it would enable hardware virtualization. This was not the right choice.

I spent many hours trying to understand why I couldn't get any hardware virtualization to work. I downloaded securable (https://www.grc.com/securable.htm) and CPU-Z to verify, neither identified any hardware support. So I got pissed off and disabled it in the BIOS to see what the hell the difference is, and viola, it works! This is the most infuriating experience, when a BIOS setting is the exact opposite of what it's supposed to be. This clearly shows that the BIOS wasn't even remotely tested for this setting, as any basic QA would have caught this in a matter of seconds. This is crap.
 
That's bizarre, the setting works as intended on my S55-A5279 -- I believe we have the same Toshiba VG10S motherboard. I tested with GRC's securable as well and it read the correct values when set to VT-x only and Disabled. Maybe you just have to reset BIOS settings to default to make it behave properly?

What BIOS version does your laptop have? Mine has 1.10. I'm curious if the P50 and S55 share the same BIOS version. :) Also, could you dump your BIOS if possible? Here's a tool to do it with: http://forums.mydigitallife.info/threads/9856-Universal-BIOS-Backup-Toolkit

I tried dumping the BIOS, but it just popped up an error message stating "Error, the BIOS could not be detected".
