I believe the Next Generation Computing is Software Defined Infrastructure on top of the robust physical infrastructure. You can ask me anything about enterprise infrastructure (virtualization, compute, storage, network) and we can discuss it deeply on this blog. Don't hesitate to contact me.
Running VMware ESX inside a virtual machine is a great way to experiment with different configurations and features without building out a whole lab full of hardware and storage. It is pretty common to do this on VMware Workstation nowadays — the first public documentation of this process that I know of was published by Xtravirt a couple of years ago.
But what if you prefer to run ESX on ESX instead of Workstation?
