Hyper-V
CentOS at Hyper-V does not connect to the internet
1. Make sure you uncheck Secure Boot in the firmware section
2. I had to force the network adapter to release and renew the IP Address to get it to pull an address from DHCP. Used the commands
sudo dhclient -r
then ran
sudo dhclient
to request an address. After I did that I was up and running and could ping anything in my network.
