[kwlug-disc] Problem reaching server

[CrankyOldBugger]

That didn't seem to help.  I commented out all of the lines below virbr0.
Now I can't reach the VMs either.

By bridging, I assumed you mean virbr0, which we all worked so hard to set
up a few weeks ago.  I don't understand why I've been merrily rebooting
since then but all of a sudden it starts to fail.  Just weird.

I'll fiddle with it some more tomorrow.
