"My VT-X is turned off", says VirtualBox

[etnguyen03]

So my problem is when I try and power on my XP VirtualBox I get the following error:

Failed to open a session for the virtual machine XP Mode.

VT-x is not available. (VERR_VMX_NO_VMX).

Result Code: E_FAIL (0x80004005)
Component: Console
Interface: IConsole {db7ab4ca-2a3f-4183-9243-c1208da92392}

Yes, I am sure that my VT is turned on. I am running Windows 8 with a HP Pavilion DV7-6c43cl that I upgraded.

Output of systeminfo | find "BIOS:

BIOS Version:              Hewlett-Packard F.13, 12/5/2011

Thank you!

An attached log file would help.

A log file. I also found a VBox.log.1-3.

Please check your BIOS settings. Looks like VT-x is disabled in the BIOS. If that does not help, check if a BIOS update is available.

Actually you are running VirtualBox is guest. Most likely because you are using Hyper-V. That's not supported.
