Hello everybody,

Here again with a Xenbr0 bridge problem
I'm a Gentoo user, xen-sources-2.6.34 and I always used the bridge from eth0 to xenbr0.
Here's what I get at boot time:
* Bringing up interface eth0
*     null
[...]
* Starting Xen control daemon ...

And the bridge doesn't come up.

The normal behaviour should be that the Xenbr0 bridge comes up automatically, but it doesn't anymore.
Here's my network configuration file (/etc/conf.d/net):

config_eth0=( "null" )

bridge_xenbr0="eth0"

brctl_xenbr0=(
"setfd 0"
"stp off"
)

config_xenbr0=(
   "dhcp"
)

I don't understand why, the bridge doesn't come up.

This is the output of the ifconfig command:

          inet addr:127.0.0.1 Mask:255.0.0.0

Can somebody help me to understand why the xenbr0 bridge no longer comes up?
