Nested ESXi 5.1 with Intel Nehalem L5520 CPU's

Hi,

I am having difficulty setting up the nesting of ESXi 5.1, hope you can help please.

I have a physical DL350 G6 with Intel L5520 CPU's, which support both VT-x & EPT.

I have followed the guide in this blog post

http://www.virtuallyghetto.com/2012/09/having-difficulties-enabling-nested.html

I have enabled vhv on the physical host.

I have enabled hardware virtulisation on each nested host.

I have also followed the procedure for enabling EVC on the cluster for Nehalem CPU's and then copying out the CPUID settings, but once I do this I cannot power on the ESXi nested hosts, I get this error "The processor does not support a required feature for this virtual machine. The virtual machine cannot be powered on."

This is the Intel CPUID settings, that I copied from the cluster and entered into each of the nested ESXi hosts

Without amending the CPUID settings I have had a 64-Bit VM running but I cannot vMotion this between the two nested ESXi 5.1 hosts.

Any help would be appreciated.

Thanks

Scott
