  Have you read OVH's failover IP guide? It's not hard at all, just use main IP w/ .254 (Edited, sorry!) as gateway, netmask .255.

  • Make sure the network connection is Bridged.
  • Make sure you generate a Virtual MAC as vmware, in OVH panel for the failover IP address you wish to configure (can take some time to get generated)
  • Copy that Virtual MAC into the Network Adapter of your virtual machine

  For the example below, let's assume your host server public IP address is: 34.34.34.34 (this is not the failover IP, but the main IP address of your server)

  On the guest Ubuntu edit the /etc/network/interfaces as follows:
  auto lo eth0
iface lo inet loopback
iface eth0 inet static
address FAILOVER_IP
netmask 255.255.255.255
broadcast FAILOVER_IP
dns-nameservers 8.8.8.8
post-up route add 34.34.34.254 dev eth0
post-up route add default gw 34.34.34.254
pre-down route del 34.34.34.254 dev eth0
pre-down route del default gw 34.34.34.254


  Notice the last 4 lines have the main server IP address, except ending in 254.

  On the guest Ubuntu do:
  ifdown eth0 && ifup eth0
  or reboot.

  Hope this helps.

  Just did that yesterday and was pretty frustrated at first.

  Suppose your main IP is A.B.C.D, and your FO IP is R.S.T.U, then configure as:

  • Address R.S.T.U
  • Mask 255.255.255.255
  • Gateway A.B.C.254

  Also you need to generate a MAC in the OVH control panel, and fill the MAC into your VM NIC settings in ESXi or whatever you use.
