We introduced a second switch into the stack and it seems like it was our bond interface to the switch that caused this particular issue. We were using bond mode 5 since that works for us elsewhere and did not think that this could be the problem since we were seeing the arp-replies reach the host bridge interface. As per Xen recommendations I tried mode 7 but that too did not work. Once configured to use bond mode 1 (active-backup) this all started working again. Apologies for the run-around, the false accusations and also the cross-posting, have a few hours before going live with this platform and was under a fair amount of pressure. All good now!! :) Regards, Gavin > >

Unless the version number changes in which case you get a new file in addition to the older version, but that doesn't apply here. > Are there any better ways to trace where this arp reply is being lost > apart from just tcpdump ? tcpdump is what I would use. > If the kenrel hasn't changed and you are 100% sure the network configuration before and after the reboot is the same then so am I. All I can suggest is to reinstall the previous version of Xen.
