I am running Centos8 under qemu installed from the same iso...
I ran:
nmcli d to get a list of "nic cards".
As root, I edited (with nano)
/etc/sysconfig/network-scripts/ifcfg-<your device> and changed to
ONBOOT=yes. Then I ran
systemctl reboot. I now have internet access.
Next follow the link:
https://www.golinuxcloud.com/install...rhel-centos-8/ to install gnome, turn it on and make default at boot.
Run
systemctl reboot et voilà
