Nested ESXi5.0 - Installation Issue

Hi

This is my first Qustion in VMTN.

I have ESXi5.1 on baremetal,  Trying to install ESXi5.0 as vertual - means vESXi5.0. I selected "Thick Provision Eager Zerod" as disk provision.

Also did,

vhv.enable = TRUE and Vmware 5.x experimental as Guest Os

thing is, the disk is not detected when trigger vESXi5.0. What could be the problem and fix?

Thanks
