I have got problem on XenServer with IP FailOver in OVH. I did everything what is in this official tutorial and IP not working. On my VM is Debian 7 64bit

I set MAC adress in XenCenter for this Network on this VM and configured network

My /etc/network/interfaces (I hide my IP now):

auto lo
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet static
address 94.XX.XXX.219
broadcast 94.XX.XXX.219
post-up route add 37.YYY.YYY.254 dev eth0
post-up route add default gw 37.YYY.YYY.254
post-down route del 37.YYY.YYY.254 dev eth0
post-down route del default gw 37.YYY.YYY.254

When I ping i have responde

root@xen-1:~# ping
PING ( 56(84) bytes of data.
From 94.XX.XXX.219 icmp_seq=1 Destination Host Unreachable
From 94.XX.XXX.219 icmp_seq=2 Destination Host Unreachable
From 94.XX.XXX.219 icmp_seq=3 Destination Host Unreachable
From 94.XX.XXX.219 icmp_seq=4 Destination Host Unreachable
From 94.XX.XXX.219 icmp_seq=5 Destination Host Unreachable

Have anybody any idea how to fix this? Thanks.
