I have HP Pavilion 15-e037cl Notebook PC with win 8.1 Pro (which I had to upgrade from win 8.1 to get option to have Hyper-V feature), and then create my first VM. I created VM successfully, but can't connect to Internet from VM.
It seems like VM can't recognize Realtek network drivers for windows 7. I had initially windows XP Home Edition installed but had the same issue connecting to Internet. I tried to installed network drivers for this windows, but wasn't sure if I had right version of the drivers. So I upgraded VM operating system to win7 home basic, but still have the same issue. I believe I have now right version of network drivers, but still can't connect to Internet, and VM isn't recognizing drivers.
I did download them from HP Support web site ...
I have installed 2 drivers on VM:
