By the way when i checked my ESXi VMs (Summary Tab) they say vmotion, ECV and Fault Tolerance as N/A. That's how i came to the conclusion that they were not supported unless you have VT-x/EPT.
These are among the many reasons that ESXi in a VM is only supported under Workstation "for educational and demonstration purposes only." However, you can get these things to work with some effort.
Again it was my pet peeve against Intel where you have to be very careful on the CPUs you buy as against AMD. All AMD CPUs support AMD-V with RVI.
That's not quite fair. Early AMD64 parts supported neither. Then there were AMD64 parts that only supported AMD-V, but not RVI...and the AMD-V support had a serious design flaw. Only since Barcelona have all AMD64 parts supported AMD-V and RVI.
Your Xeon pre-dates Intel support for EPT. Since Nehalem, all Intel CPUs with VT-x support also support EPT. Having said that, it is true that some Intel skus do not have VT-x support at all.
