[Xen-users] SLES10 SP1 - xen bridges break after update

Hello all,

I upgraded a SLES10 to SP1 yesterday, xen-3.0.4_13138-0.40.

I have dot1q setup there, 3 physical interfaces (eth0, eth6 and eth7)
each one on a different vlan.

I have this custom network-bridge script, common one, called from
xend-config.xsp:

#!/bin/bash

dir=$(dirname "$0")
"$dir/network-bridge" "$@" netdev=eth0 vifnum=0
"$dir/network-bridge" "$@" vifnum=6 bridge=devnw netdev=eth6
"$dir/network-bridge" "$@" vifnum=7 bridge=testnw netdev=eth7

At server reboots, no bridge at all comes up. If I launch it manually
afterwards, I get:

bornem2:~ # /etc/xen/scripts/custom-network-script start
    eth0      device: Intel Corporation 82547GI Gigabit Ethernet Controller
    eth0      configuration: eth-id-00:04:23:b8:1b:8a
    eth0      IP address: 172.17.8.14/24
    eth0      device: Intel Corporation 82547GI Gigabit Ethernet Controller
    eth0      configuration: eth-id-00:04:23:b8:1b:8a
Nothing to flush.

    eth0      IP address: 172.17.8.14/24

Link veth6 is missing.
This may be because you have reached the limit of the number of interfaces
that the loopback driver supports.  If the loopback driver is a module, you
may raise this limit by passing it as a parameter (nloopbacks=<N>); if the
driver is compiled statically into the kernel, then you may set the
parameter
using loopback.nloopbacks=<N> on the domain 0 kernel command line.


Link veth7 is missing.
This may be because you have reached the limit of the number of
interfaces BLA BLA BLA

I am allowed up to 64 loopbacks, so this isn't the problem.

ifconfig looks like this, after launching the script manually:

Well, has anyone seen this yet? What other info can I provide you guys
to better understand the problem? It worked perfect on SLES10 without SP1...

Thanks a lot.
