Re: [Xen-users] xen 3.1 network configuration problem

Hello,
I am trying to use XEN networking as default : bridge xenbr0 with
ethernet adaptor eth0. As soon as xend is started , xenbr0 does not
activate and eth0 seems to run as if no bridge were preent.
Here is my config file:
# To bridge network traffic, like this:
#
# dom0: fake eth0 -vif0.0 -+
# |
# bridge -real eth0 -the network
# |
# domU: fake eth0 -vifN.0 -+
#
# use
#
# (network-script network-bridge)
#
# Your default ethernet device is used as the outgoing interface, by
default.
# To use a different one (e.g. eth1) use
#
# (network-script 'network-bridge netdev=eth1')
#
# The bridge is named xenbr0, by default. To rename the bridge, use
#
# (network-script 'network-bridge bridge=<name>')
#
# It is possible to use the network-bridge script in more complicated
# scenarios, such as having two outgoing interfaces, with two bridges,
and
# two fake interfaces per guest domain. To do things like this, write
# yourself a wrapper script, and call network-bridge from it, as
appropriate.
#
(network-script 'network-bridge bridge=xenbr0 netdev=eth0')
# The script used to control virtual interfaces. This can be overridden
on a
# per-vif basis when creating a domain or a configuring a new vif. The
# vif-bridge script is designed for use with the network-bridge script,
or
# similar configurations.
#
# If you have overridden the bridge name using
# (network-script 'network-bridge bridge=<name>') then you may wish to do
the
# same here. The bridge name can also be set when creating a domain or
# configuring a new vif, but a value specified here would act as a
default.
#
# If you are using only one bridge, the vif-bridge script will discover
that,
# so there is no need to specify it explicitly.
#
(vif-script 'vif-bridge bridge=xenbr0')

An ifconfig gives the following:

Here is the result of the command:

peth0
I enclosed the log files generated by xen for the command line :
service xend start :
I have no idea of the reason why the xen network does not start. (Do I
need a package which is not present ?)
If anyone could give a way where to investigate ...
Thx a lot

As far as I see the ifconfig command says that the bridge is there?
The eth0 is normal. I only dont know why you have ip address assigned
for xenbr0?
I dont see anything bad on your configuration. Tell us what does not work?
For domU you have to then specify the bridge in domU config.
For comparison here is mine with more bridges.
