Ok, im having an issue our xen networking once I updated to 3.4.1 on my Centos 5.3 box. I''ve documented it here: Error in /var/log/messages: Sep 9 03:01:03 wheeljack logger: /etc/xen/scripts/vif-bridge: iptables setup failed. This may affect guest networking. NOTE: vif-bridge is stock that comes with 3.4.1 part of xend-config.sxp: (network-script network-bridge-wrapper) (vif-script vif-bridge) [root@wheeljack ~]# cat /etc/xen/scripts/network-bridge-wrapper #!/bin/sh /etc/xen/scripts/network-bridge $1 netdev=eth0 /etc/xen/scripts/network-bridge $1 netdev=eth1 ifconfig is giving me: eth0, eth1, eth2, eth3,peth0, peth1, lo, and virbr0 btw, I upgraded from 3.3.1 to 3.4.1. I know it says the error is with vif-bridge, but that''s stock, so I don''t know what could be wrong with it. any ideas?

Mark, What does your iptables config look like? ...adam ________________________________________ From: xen-users-bounces@lists.xensource.com [xen-users-bounces@lists.xensource.com] On Behalf Of Mark Chaney [macscr@macscr.com] Sent: Thursday, September 10, 2009 1:37 AM To: Xen-users@lists.xensource.com Subject: [Xen-users] networking issue after upgrading to 3.4.1 Ok, im having an issue our xen networking once I updated to 3.4.1 on my Centos 5.3 box.

This may affect guest networking.Is it REALLY a problem, or is it just some noisy log? As I recall there was a feature in iptables that is used by vif-bridge (probably physdev match, I can''t remember the exact one) that cause iptables to spit out warnings that it will be unsupported in the future. You should be able to see the exact message on console. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

RE: [Xen-users] networking issue after upgrading to 3.4.1
OK, I actually have iptables completely disabled at this point. There is definitely something wrong with xen networking for me as its causing the dom0 to get fenced from the cluster. This only happens if I have a guest running on the dom0. Its not immediate though, happens randomly. But as often as every hour or two. The dom0 is rock solid though if no guests are running. My question though, is that if any major network changes have happened between xen 3.3.1 and xen 3.4.1, why arent they documented anywhere. The xen networking wiki hasnt been changed since Feb, so i wouldnt think there were any. =/ -----Original Message----- From: xen-users-bounces@lists.xensource.com [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Wead, Adam G Sent: Thursday, September 10, 2009 7:50 AM To: Mark Chaney; Xen-users@lists.xensource.com Subject: RE: [Xen-users] networking issue after upgrading to 3.4.1 Mark, What does your iptables config look like? ...adam ________________________________________ From: xen-users-bounces@lists.xensource.com [xen-users-bounces@lists.xensource.com] On Behalf Of Mark Chaney [macscr@macscr.com] Sent: Thursday, September 10, 2009 1:37 AM To: Xen-users@lists.xensource.com Subject: [Xen-users] networking issue after upgrading to 3.4.1 Ok, im having an issue our xen networking once I updated to 3.4.1 on my Centos 5.3 box.
