I have an old PowerEdge 860 that I would like to use for some XenServer testing. It currently has an Intel E4500, 2.20, 2M, CORE DUO-CONROE, which does not have Intel Virtualization Technology (VT-x), so it'll limit the Xen functionality (if it even works at all.) I would like to replace the processor with something that has VT-x, or alternatively, replace the motherboard and processor. What are my options? Thanks in advance for all the suggestions.
