[Xen-users] Trouble with bonding + arp_ip_target + vlan + trunked netdev + network-bridge script
Running debian lenny with 3.2.1 + 2.6.26. Even tried 2.6.35 suse kernel and xen 4.0.0 but still the same problems. Running bonding on eth0,1 as bond0 with arp_ip_target as check to see if interfaces really are online. Problems start when i run: /etc/xen/scripts/network-bridge start netdev=bond0.120 Then the arp_ip_target in the bonding driver completely freaks out: Jul 22 16:34:21 kernel: [ 709.844231] bonding: bond0: no path to arp_ip_target 77.xxxxxxx via rt.dev bond0.120 Jul 22 16:34:23 kernel: [ 711.848233] bonding: bond0: no path to arp_ip_target 77.xxxxxxx via rt.dev bond0.120 Jul 22 16:34:25 kernel: [ 713.852232] bonding: bond0: no path to arp_ip_target 77.xxxxxxx via rt.dev bond0.120 Jul 22 16:34:27 kernel: [ 715.856350] bonding: bond0: no path to arp_ip_target 77.xxxxxxx via rt.dev bond0.120 Jul 22 16:34:29 kernel: [ 717.860232] bonding: bond0: no path to arp_ip_target 77.xxxxxxx via rt.dev bond0.120 It then starts to jump back and forth between eth0 and eth1 because both doesnt seem to get arping reply through rt.dev bond0.120. Whats strange is that arping works: # arping -i bond0.120 77.xxxxxx ARPING 77.xxxxxxxx 56 bytes from 00:10:db:ff:20:50 (77.xxxxxxxxx): index=0 time=535.011 usec 56 bytes from 00:10:db:ff:20:50 (77.xxxxxxxxx): index=1 time=4.130 msec Anyone else seen these problems? This only happens after network-bridge creates the bond0.120 bridge which pbond0.120 is attached to. (bond0.120 has ip, pbond0.120 does not) --- Mvh Rolf Arne Larsen System Administrator rolf@startsiden.no ABC Startsiden AS Sagveien 21A, 0459 Oslo _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Yes. Am pretty sure, hit me on an update running "standard" CentOS Xen Virtualization install. Arpwatch showing flip flops. Bridges either don''t work, or get intermittent dropping. "vibr0" nat type seems to work. Isolated bridges to nics do not. May be hardware specific. I''m working on installing to different hardware.
