T400 virtualization fails despite set in BIOS
I found this post http://forums.lenovo.com/t5/ThinkPad-Edge-S-series/Hardware-Virtualisation-on-E520-with-i5-2540M-2-6GHz/td-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.
vmx is enabled per "grep vmx /proc/cpuinfo"
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.
