All used information to install I found here:
Using things:
- EVE-PRO meaning with license
- CentOS CentOS-8.1.1911-x86_64-dvd1.iso
Step 1. Download CentOS – donloaded from Download CentOS version Linux DVD ISO
See 2. Go into EVE-PRO and move into qemu directory

root@eve-ng:/opt/unetlab/addons/qemu# cd linux-centeros-8
root@eve-ng:/opt/unetlab/addons/qemu/linux-centeros-8#
Step 4. Upload CentOS-8.1.1911-x86_64-dvd1.iso in EVE-PRO using FilaFilla application
root@eve-ng:/opt/unetlab/addons/qemu/linux-centeros-8# ls
CentOS-8.1.1911-x86_64-dvd1.iso
Step 6. Create qcow2 file

All 3 can power-on …
Step 14. Configure and Mange Network Connection using nmcli
The needed information I find here: How to configure and Manage Network Connections using nmcli. I use The nmcli connection sub-command chapter.
# nmcli connection show

I can see this but I modify using nmcli command
I hope all detail help me and you in future use.
