I had a case where I was building an image for windows 2008. The host uses 10 GB NICs and for some reason, they were not recognized.

I would add them to the configuration, reboot and nothing happened. I installed Xentools and nothing happened. Thinking it might be the age old driver issue but I did not find any on the vendor site. Setup issue?

To get around this “feature;” you have to delete all NICs and then add the one you want.

A quick reboot and the network was available.
