Hmm, must be a Xen 3.2 addition then. It seems to come into
existence when I bring up a domain and disappears after I
destroy it, so it's related to the networking of domains,
but I'll need to look into this further.

So you have multiple gateways setup with different weights?

If so that could also explain it. If your private IP is, based on your earlier post, that would make
perfect sense.

Anyways, yes the older scripts will need to be fixed up
to handle the iputils output and if you get them working
well file a bug report with the fix.
