Small Business Server with Hyper-V role despite it not being supported?

We've put Hyper-V on SBS. In these days where servers are ridiculously powerful it seems an obvious option and we've found it to work just fine as long as you don't run anything too heavy in the VMs.

We use Dells that have two NICs built in. We set up SBS with NIC2 disabled. Once it's all working enable NIC2 then install Hyper-V (and reboot). Now create a Hyper-V network on NIC2, then on the host disable the resulting synthetic NIC.

So the host now has NIC1 untouched by Hyper-V and used for the normal SBS operations, and a disabled synthetic NIC. DHCP and indeed all aspects of SBS work fine. The VMs use the virtual network on NIC2. Disabling the synthetic NIC on the host does not affect the VMs.

We've done the reverse.... install a system with hyper-v and then virtualized sbs. This has the disadvantage that the usb disk backup and ms fax server are not supported (both for the same reason - lack of usb support in hyper-v) but it works just fine.

We've only done this in networks where we've had DCs on other boxes, otherwise the hyper-v machine boots and doesn't see a Dc until it boots it sbs client... not exactly desirable.
