No, I havent been able to fix this. I suspect this is a problem of the nested setup, not a problem as such. In my test lab at work, such a setup works with no problems. Another problem of the nested setup is when you attempt to move the management network of your vESXi's, they drop off the network and only come back when you restore the management network to OOBE.
If I ever get this fixed, I'll definitely report back. Anyone have any pointers?
