OK, next dumb question: Now the NM applet says the wired network is "unmanaged".
It WAS, a couple days ago, working via NM, as I could plug in the cable and
the little icon in the top panel went round and round then it connected.
Today it's not doing anything even if I forcefully disconnect wireless first.
I suppose I must have changed something, but again I can't see what that
would have been.

once again, advice will be appreciated, thanks!
In System > Administration > Network, if your adapter is listed, edit
its settings and make sure "Controlled by NetworkManager" is
selected.  If you don't see the adapter that's not ipso facto a
problem, but my bet is you will.
Paul, you hit the nail on the head. Thanks for the tip!

Perhaps I can throw out ONE MORE networking question...

I keep seeing this in the output of /sbin/ifconfig:

virbr0 link encap:Ethernet HWaddr 5A:4C:8D:5F:54:EA inet addr: Bcast: Mask:
          inet6 addr: fe80::584c:8dff:fe5f:54ea/64 Scope:Link
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:28 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:4977 (4.8 KiB)

but I have never configured anything named "virbr0" or even close to it.
My LAN is not 192.168.122. I don't know where this comes from. Or what
is the proper way to get rid of it.

I've never encountered anything like it on any other Linux box (of which
there have been many under my care) so I'm a little nervous about just
whacking it.

Thanks, once again!

That's a virtual bridge adapater provided for the benefit of any
virtual guests you might later use.  It's normal and safe to ignore,
or IIRC you can simply turn the libvirtd service off to make it

I find that with F10 then KVM networking almost but not quite works as expected. It seems that regardless of the command line kvm options, I get the internal network, 10.x.x.x, and the associated DNS. Since I have given the correct MAC address to use, I have not found a reasonable way to get kvm to pass the MAC address up directly and get an IP from my internal dhcp server. Since this works on my two existing FC6 kvm servers, something has changed over time, and I can't find a doc for it.

This results in packets using the kvm host MAC address, not at all what I want, since I would like to move some of my virtual servers to a newer release and hardware. I can probably hack things to get it working, but I assume there's a more correct way than building and configuring all my own bridge stuff, etc.

Any pointer to doc on this? I need to start servers on demand and without a human in the loop, so cute GUI managers aren't the solution.
