...-bridge scripts breaks the network. I have run through the commands manually in irder to establish the culprit. In the op_start function (Starting on line 214) everything is fine up until line 251. At this point the bridge has been created, devices renamed and the network is fine, but then it runs do_ifup {$bridge}. In this function on line 111 it does ifup $1. This breaks everything. My solution is to surround the do_ifup ${bridge} line with a condition: if [ ! -n "${slaves}" ]; then do_ifup {$bridge} fi -- System Information: Debian Release: 6.0.3 APT prefers stable APT policy:...

Apologies, there is a slight change required to the solution. replace the do_ifup line as follows: if [ -n "${slaves}" ]; then ip link set dev $bridge up [ -n "$gateway" ] && ip route add default via ${gateway} else do_ifup ${bridge} fi -- Philip Ward Unix Systems Administrator 01786 467274 (ext 7274) --...

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 / br...

...rce.com/bugzilla/show_bug.cgi?id=1655 The fix is to turn off UDP checksum offloading on the vif interface in Dom0 as documented in the above mail: I edited /etc/xen/scripts/network-bridge, adding this command to the end of the op_start() function: add_to_bridge2 ${bridge} ${pdev} do_ifup ${netdev} + # disable ip checksum offloading for veth device + ethtool -K ${netdev} tx off else # old style without ${vdev} Note: I am not sure which path is taken through the script, I set the parameter manually with ethtool before I found this patch.

Hello I use XEN 3.0 in debian sarge. I have a domU1 for routing and firewall. This domU1 use 2 network interfaces which is on a bridge ''gate'' and the other on bridge ''lan''. dumU2 use one interface (eth0) on bridge ''lan''. Then I make a ping out of domU2 to www.debian.de so I get no answer. The name isn''t resolved. A ping to IP of

...but connected to a network to which the DomUs are supposed to be connected. This setup does not work with the network-bridge script, because it does not bring eth0 up, after it became the bridge and in consequence the DomUs do have link, but no network connectivity. I guess the problem lies in the do_ifup function which tries to call ifup to bring the new interface (bridge with the name of the original eth device) up. There is an alternative code path which I guess is supposed to be called if devices are not in /e/n/interfaces, where the script expects that ifup would exit with a non-zero exit code....

Hi, I''m using Xen 3.0.3 on two servers with Debian Etch (amd64). These servers have 10 nics (2 onboard and 8 in two 4-port cards) so that every vm can have its own interface. This worked so far with the Xen Version from Etch with a wrapper script wich started 10 bridges at boot time. But now I''ve updated Xen on one of these server to Xen 3.2.0 from backports.org and now the
