I have no clue what is hosting itself on 192.168.122.1
Do I kill it somehow and were is it? I'm looking all through /etc and
not finding it. Someone please clue me in. Ric

It smells of xen.

If you don't use xen, just remove it.

"virbr0 192.168.122.0" is the virtual bridge network created by F8 VM
(virtual machine) implementation.
All guest machines hosted by the host machine will be part of this
192.168.122.0 network. I imagine
you installed some package from the 'Virtual Machine' group. If you
don't really need it, you can remove

the VM option and I think F8 would clean itself up.

Thanks! I'm running F7 and I'm not sure what package is in that "virtual
machine" group. Would that be something like zen? Is it doing any harm?
I just was wondering what the heck it was and network manager wasn't
showing or controlling it. Merry Xmas to everyone! Ric

Hi Ric,

I don't run F7 at the moment, but with F8 Virtualization Group, I see
packages like
Kernel-xen, kvm, qemu, xen. These are all different forms of
virtualization. The bridge
network would do any harm other than taking some extra memory space.
192.168 is
a private network, so no one from the outside can get to it unless you
configure your

router or iptables to forward the traffic.

I like a simple clean system, so I would remove the packages if I'm not
doing

virtualization.

That's "Xen" and yes, that's the virtual machine stuff.

Not really. Kinda useless if you're not going to run Xen.

Network manager won't control that as it's under control of the Xen
kernel.

You know the symptoms ...the installer asks an innocent question and you
go "why the hell not?" and push the candy-like shiny red button to
confirm your choice. No smoke, no harm. Then I noted with alarm this xen
kernel and beat it out to submission. I have a stock kernel now and I
guess I just have the remnants of my original installation-time button
pushing escapade now orphaned. Thanks for the info! Red is never a good
color to push. Ric
