Using multiples interfaces -bridging- on a KVM guest

[Endorphine]

Hello all,
I needing help for this, as I tried a lot of things; all leaded to fail

I have some dedicated servers at OVH, and need to add multiples interfaces
to a KVM guest (failover IP).
They must be used as bridge, so I set virtual MAC on these IP via OVH Manager..
then I add this MAC as a e1000 interface on the guest ...

It's bridged on vmbr0 because only 1 physical ethernet card which is on
eth0<->vmbr0

Debian "interfaces" config :

auto lo eth0
iface lo inet loopback
iface eth0 inet static     <------------------------------ This one is working
address 178.33.252.IP1
netmask 255.255.255.255
broadcast 178.33.252.IP1
post-up route add 188.165.243.254 dev eth0
post-up route add default gw 188.165.243.254
post-down route del 188.165.243.254 dev eth0
post-down route del default gw 188.165.243.254

iface eth1 inet static
address 178.33.248.IP2
netmask 255.255.255.255
broadcast 178.33.248.IP2 <--------- The other one (who don't work)
hwaddr 02:00:00:xx:xx:xx
post-up route add 188.165.243.254 dev eth1
post-up route add default gw 188.165.243.254
post-down route del 188.165.243.254 dev eth1
post-down route del default gw 188.165.243.254

as soon I type "ifup eth1" .. guest stop pinging and I need to reset
the guest.

Any help would be trully appreciated (as at OVH forums they don't
have any ideas).

Lot of thanks;
Thomas
