[CentOS-virt] proper bridging technoque

[aurfalien]

OMG!!!

So let me first give an analogy.

Me;
So I have a flat tire.

You;
No, its inflated and looks fine.

Me;
No, I'm tellin ya its flat.

You;
I just checked tire pressure, all is well.

Me;
Holy sh$#, the road it jacked up giving e the illusion of a flat!

So I am able to ping my br6 int from another host so I assumed it was up.  But upon examining ip route, I see my def route is my primary interface br0 so it answered back even though I ping br6.

I walk over to the KVM host and eth6 is physically unplugged!

Its in now and all is well.

Dude, so sorry.

Now, to fix it so a ping will result in accuracy.
