Pkg xen devel - Jul 2010 - Bug#588477: network-bridge: start: 95 sec sleep/bridge without a default gateway

Package: xen-utils-common
Version: 4.0.0-1
Severity: normal
Tags: patch

do_ifup() in network-bridge exits badly, if the interface doesn't have a
default gateway.

Since it's wrapped in xen's locking script it causes it to be retied 100
times and sleep for 95 seconds before it continues.

In my setup this amounts to:
16 vlans without a default gateway * 95 secs / bridge = 25 minutes nap

Zzzz...

Please submit upstream. This configuration is discouraged in Debian.
