enp0s8 not configured notification popups every few minutes (annoying)

[Kenneth Wolcott]

Hi;

  enp0s8 not configured notification popups every few minutes (annoying)

  I just installed Fedora Live 64-bit KDE as a VirtualBox Guest OS.

  I want to have two VirtualBox ethernet interfaces:

  One for the vm to "see" outwards (NAT Network) and

  Two for me to ssh into it (Host-only) so that I'm not forced to use
the console.

  Every few minutes (it seems like every few seconds), I get a
notification popup that states that enp0s8 is not configured and then
a notification popup that it is being disabled.

  How do I configure my outgoing ethernet interface?

  I used to edit a file called something like /etc/network*/interface
and then I could change the default DHCP setting to be static and the
default disabled (off) setting to be enabled (on).

  How does one do that kind of stuff now?

  Is that a systemd thing?

Thanks,
Ken Wolcott
