SOLVED :

Here are the configuration that works for me :

On Domain0 / NetBSD 3.99.22 / Xen 3.0.2.2 :

/etc/ifconfig.bridge0 ( "re0" is my default network device )
-----------------------------------------------------------------------
create
!brconfig $int add re0 stp re0 up
-----------------------------------------------------------------------
/usr/pkg/etc/xen/xend-config.sxp : changing the following line

(network-script network-bridge)
by this one :
(network-script 'network-bridge netdev=3Dre0')

And finally : the configuration file itself :
-----------------------------------------------------------------------
kernel =3D "/root/netbsd-XEN3_DOMU"
memory =3D 128
name =3D "test"
#cpus =3D ""         # leave to Xen to pick
#cpus =3D "0"        # all vcpus run on CPU0
#cpus =3D "0-3,5,^1" # run on cpus 0,2,3,5
# vcpus =3D 1
vif =3D [ 'bridge=3Dbridge0' ]
# disk =3D [ 'phy:/dev/wd0h,0x03,w', 'phy:/dev/cd0a,0x04,r' ]
disk =3D [ 'phy:/dev/wd0h,0x03,w' ]
root =3D "/dev/wd0d ro"
-----------------------------------------------------------------------

Hope these tests will help ...

Best Regards

Arnaud.
