Hello everyone,
When I try to start firewalld in CentOS-8 it refuses with this in the
/var/log/firewalld, any suggestions?

Are you running CentOS 8 on a hosting provider that uses OpenVZ or similar
container-like VPSs?  What does ?uname -r? report?

I ask because it looks like your system can?t load the kernel modules required
to set up a firewall.
