I found when I recovered a VMs with Veeam version 8 update 2, the Nic card was not showing. This is related to the change of the MAC Address.
You need to ensure in this file :
You have only one ETH0 and also the MAC ADDRESS in this file, matches the MAC address of your NIC Card in the VMware Properties!
After to ensure your NIC configuration follow update you MAC address inside this file also.
