[ale] CentOS 7 virtual IF installed by default

[Jim Kinney]

That may be used to act as an internal gateway for virtual machines. Remove
the virtual systems rpms and it should go away.

rpm -qa | grep virt | xargs yum remove

That will test the removal for conflicts. Add "-y" after yum to actually
remove things.

Hi all,

I'm trying to get a better understanding of why CentOS installs a virtual
interface on 192.168.122.1 seemingly by default.

I'm finding it's creating trouble on my network because AD DNS is picking
up this IP on the network and adding an entry for it. I tried deleting it
(the DNS entry) but it keeps getting recreated. I could disable the
interface, but am concerned I might break something. What's it actually for
and is it safe to just get rid of it?

The strange thing is my network seems to prefer finding this virtual
interface's IP over the IP that I assigned to etho. I certainly don't want
that.

I'm running CentOS for Windows file sharing. Maybe I installed some package
that results in this virtual interface being installed, but I'm not sure
what. These boxes are really only doing Samba, although they do have a
basic GUI installed too.
