[Pkg-xen-devel] Bug#706876: xen-utils-common: network-bridge assigns addresses, breaking ifup

[Frank Lee]

Package: xen-utils-common
Version: 4.1.4-3
Severity: important

Dear Maintainer,

Executive summary: dist-upgrade - squeeze to wheezy. Rebooted machine; 
no default route on network interface eth0. Commented 'transfer_addrs' 
function in network-bridge produced a machine which worked after reboot.

We're using network-bridge as our xen networking configuration. After 
rebooting the Dom0, we had no networking via the usual eth0 bridge.Some 
digging into the problem indicated that the network-bridge script was 
assigning addresses to the newly created bridge, then calling 'ifup' on 
the same device. 'ifup' declined to operate on an interface with an 
existing address.

/etc/xen/scripts/network-bridge contains:
transfer_addrs ${netdev} ${tdev}
...
transfer_addrs ${bridge} ${pdev}
Commenting each of those lines out fixed the symptoms for me. 

Happy to provide further information if that would help.

Yours,

Frank Lee
