Running ESXi 5.1 in Hyper-V 3.x

On many websites i have read that i could not be done.
But it is possible ... running ESXi within hyper-v 3.0 (Windows Server 2012 / Windows 8)
Why ? For the fun of it and for your own lab-environment.

How do you do it:

1. Download ESXi 5.1 from VMWARE.COM
2. Download Tulip NIC driver from http://communities.vmware.com/servlet/JiveServlet/download/2187254-103100/tulip.vib
3. Download ESXi Customizer from http://www.v-front.de/p/esxi-customizer.html
4. Run ESXi Customizer
5. Load ESXi ISO file in ESXi Customizer
6. Load tulip.vib in ESXi Customizer (downloaded at step 2)
7. Create custom ISO
8. Create New virtual machine in Hyper-v and add custom esxi ISO to this virtual machine
7. Give the new virtual machine 2 virtual processors and 4 GB internal memory
8. Remove NIC and Add legacy Network Adapter to the new virtual machine
9. Start virtual machine
9. Run ESXi installer
