As my server IBM x3200 M2 and CPU (E4600) does not have VT-x for virtualization (I would like to virtualize Windows in XenServer), may I substitute this CPU for some core2duo or core2quad that supports VT-x ? Does the motherboard have to support VT-x as well or it will work ? THank you very much
Yes. You can use the E3110 (dual core), E3320, E3350, or E3360 (all quad core). Contact IBM for instructions, parts, and pricing. Only the E4600 (cheapest option) came without VT-x.
