No Network Connection on 2008 Server Guest OS on Server 2016 host Hyper-V

We have just setup a Windows 2016 Server to run Hyper-V and host 3 different Windows 2008 Servers.  I have installed all 3 of them from an ISO-image, no errors... but they do not come up with a network card.  

I did create a Virtual Switch and they are all using it.  Each of their device managers shows a single network adapter "Microsoft VMBus Network Adapter" with an error that it could not start.

I would appreciated any assistance on this.

If these are 2008 (not R2) guests then you'll probably need to add the legacy NIC to the VM.

Did you install the integration services?  Legacy NICs (I think) fall back to 100Mbit...

As I recall, 2016 components don't include enlightened drivers compatible with 2008, hence my suggestion.  I don't specifically recall the source anymore.
