<div dir="ltr">Hey everyone,
<div><br>
</div>
<div>I've been trying to configure Ubuntu LXC with 2 ip failover
from OVH but i failed :(</div>
<div>I've been reading many howto's and still nothing. I have
found on this list same cool tutorial which has written by
Olivier. There is a link: <a moz-do-not-send="true"
href="https://lists.linuxcontainers.org/pipermail/lxc-users/2011-May/001980.html">https://lists.linuxcontainers.org/pipermail/lxc-users/2011-May/001980.html</a></div>
<div><br>
</div>
<div>I don't know why i still can't get access to internet from
LXC.</div>
<div><br>
</div>
<div>My host ip: <span
style="color:rgb(116,116,116);font-family:OpenSans;font-size:14px;line-height:20px;background-color:rgb(245,245,245)">94.23.237.216</span></div>
<div>My ip fail over ip 1: <span
style="color:rgb(116,116,116);font-family:OpenSans;font-size:14px;line-height:20px;background-color:rgb(245,245,245)">91.121.239.228</span></div>
<div><br>
</div>
<div>I'll focus on one failover ip. </div>
<div>I did as Olivier has subscribed.</div>
<div><br>

<div>Host:</div>

<br>
Use either post-up and /sbin/ip or 'iface br0:0 inet static.....'.<br>

Use this IP either here or on the bridge iface, but not at both
places.<br>

Define your network either in container:/etc/network/interfaces or
in lxc config file, but not at both places.<br>
