True, it is manual, but it's a bridge. I can't seem to find it now, but that's precisely how it was supposed to be configured, according to the documentation I was going by (I think it was one of the KVM oriented guides). And, no, it's not showing up when I do a brctl show on this one server (it shows up fine on the other *identical* server). >> Any idea why it isn't coming up automatically on boot, when my other > > Because 'manual' means 'unconfigured', different from 'static' which > means manually pre-configured. > But the other server with identical hardware, and identical config, and identical interfaces file (except for 2 lines where ip addresses are specified), works differently. On that box, the bridge shows up fine using brctl show. Thanks, Doug >> identical machine does just fine? Or even where I might look to try >> and figure it out myself?
