Windows SBS 2008 and Hyper V

So a situation arose at work where it became necessary to install the Hyper V role inside Windows SBS 2008 Std Edition. Everything I read was basically saying not to do this, Microsoft doesnt support it, no one supports it, dont pray to God when it doesn't work because even he doesn't support it.

Well I did it and sure enough I broke something...well a few things actually. Firstly DHCP stopped working as everyone said it would. Then the network started doing really strange things and basically I thought that my new nice clean server was going to end up bricked.

However to cut a long story short it is possible to do it and I have got it working. I now have a Windows XP machine humming along quite merrily in a Hyper V session inside SBS08 and it has been for the last couple of months. The critical mistake that I made was not to install a second network card and use it exclusively for the virtual machine. Because I didnt do this the first time round all of the virtual network settings tried to bind to the main NIC and ended screwing everything up. With its own dedicated NIC everything has been working just fine....and yes I know....its not supported.
