T400 virtualization fails despite set in BIOS

I found this post http://forums.lenovo.com/t5/ThinkPad-Ed ... d-p/608633 when I searched on 'T400 Virtualization' - but running through its steps did not help. I have a T400 with the BIOS version 2.16 7VET6WW dated 2009-04-22 with system board vf27k9434tj and the Intel P8600 CPU.

I try to set up virtualization with VirtualBox on Linux Mint 17 'Quiana' but VirtualBox tells me I do not have VT-d enabled, even though it is enabled in the BIOS, and I have cycled power since changing the BIOS.

No supervisor password is set. The RAM matches, a pair of 2GB modules.

How can I get virtualization to permit use of multiple CPUs?

Thank you kindly.

Did you check what appears in dmesg about virtualisation?
Check the following in a terminal

Code: Select all

dmesg | grep -i iommu
dmesg | grep -i vt-
dmesg | grep -i virtualisation

Maybe you need to set a kernel parameter to activate it.
