This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Have a look at this SF question… – Iain Oct 27 '10 at 11:43
Why do you want to? – Bart Silverstrim Oct 27 '10 at 11:54
'Cos you've watched Inception one too many times ;-) – Gaius Oct 27 '10 at 11:57
1 bluescreen each WinVM in succession to get back to the host? – Bart Silverstrim Oct 27 '10 at 12:06

Not seriously. YOu can with software simulation (slow). But hardware virtualization (fast) only supports ONE layer. Because noone seriously needs more.

The ServerFault question is slightly out of date, and I only know the answer for the VMware platform. Short answer: yes, with restrictions. The latest versions of Workstation and ESX support running the latest version of ESX inside a VM for demonstration purposes. You can then build up a guest VM and run that from inside the guest ESX instance. You do need to edit the VM config though to turn on some advanced options.

Here's some info:

Again, VMware does support this configuration, but only for demonstration purposes.

There's talk that it is also possible with VirtualBox too. – user48838 Oct 28 '10 at 8:19

I have had success in running ESX under fusion 2.0, with several VMs but as other have mentioned it did require a bit of tweaking to get it running. I assume this is mostly for testing so I can see the reasons for doing it as was with my case. I cant imagine anyone doing this for production.

Also, as someone did point out it does require a bit of resources but I was able to manage all this on a mac pro with 4GB.

You can but you would be highly limited to resources. I recommend VirtualBox for something like this... and a lot of RAM
