        Don't use network-bridge to start the bridge. As someone has recommend,
just use network-dummy and configure the bridge in a debian way. This is
my configuration (I'm using bonding, active-backup, and vlan):

auto bond0
iface bond0 inet static
        address <ip>
        netmask <netmask>
        network <network ip>
        broadcast <broadcast ip>
        gateway <gateway>
        # dns-* options are implemented by the resolvconf package, if
        dns-nameservers <dns>
        slaves eth0 eth3

iface vlan212 inet manual
        pre-up /sbin/ifup bond0
        vlan-raw-device bond0

iface xen-br212 inet manual
        pre-up /sbin/ifup vlan212
        bridge_ports vlan212
        bridge_fd 0
