Getting weirder.
I reinstalled a third node from scratch with no bonding and my VM works
fine.
To answer an earlier question, we're not configuring any bonding on the
data center switches so I've stuck to bonding modes like round robin,
active/stand-by, and XOR. I've mostly been using XOR.
Where it gets weird is if I switch the bonding mode from XOR to
active/stand-by, a VM on that host can see the real world. And if I
switch it from active/stand-by back to XOR, it still works.
I'm currently running three nodes, all with bonded interfaces in XOR
mode, and all is well. I wish I knew why.
