If you are using ethernet (and not a wireless device or some other internet connectivity) you should have an ifcfg- file for the interface.

I tried to boot a Centos 8.2 install CD, one burned with Centos-8-2-2004-x86_64-boot . In the setup, it persisted in telling me that ethernet thing enp0s25 was disconnected. Nyet. 'Twas working several seconds previous and is working now. This is a showstopper. How do I debug it? Also, whatever else it did, I now have environment variable HOSTNAME=2001-48F8-3004-2CE-1AE9-F1BF-8759-FF4C-dynamic.midco.net . It shows up on my terminal window headers...

...This could also be related somewhat to https://www.redhat.com/archives/libvir-list/2013-September/msg01311.html but I suppose it is not exactly that thing. I've already figured the source of trouble is anyway related to these rules added: -A POSTROUTING -o br0 -j MASQUERADE -A POSTROUTING -o enp0s25 -j MASQUERADE -A POSTROUTING -o virbr2_nic -j MASQUERADE -A POSTROUTING -o vnet0 -j MASQUERADE Here, virbr2_nic and vnet0 are used by libvirt for arranging network configurations for VMs, ok. However, br0 is a main interface of this host with primary ip address, with enp0s25 being a physical nic...
