you have hosted ESXi on Hyperv 2016,whether I'm correct?If yes what is the generation you have selected to host the ESXi in Hyper-V.Prefer to go with Gen1 which suits most of the Operating system and network card as legacy which suits most of OS.
I choose the generation 1 model in hyper v.
I think you have just customized image and not injected into the ESXi operating system.
But the command -load net-tulip dont inject the driver in esxi operating system?
I see the following message when i create the iso:
Load additional VIB net-tulip from online depots...
Add VIB net-tulip 1.1.15-1 [New AcceptanceLevel: CommunitySupported] [OK, Added]
