The 2457M is not on the Intel processor roadmap. The Lenovo page lists the i5-2537M or i7-2617M. If you are interested in the i5-2537, it does support Intel VT-d and Vt-x. If you are looking at a different web page on the Lenovo site that lists the i5-2457M, please contact Lenovo to find out what the real options are.
