Od kilku dni strasznie się męczę z konfiguracją IP pod LXC (ktore mam od OVH jak i serwer) i nie mogę dojść do ładu i składu. Posiadam serwer w OVH z IP: 94.23.237.216. Dokupiłem też jedno IP zwane failover: 91.121.239.228. Failover chciałbym podpiąć pod LXC.

Z góry dziękuję,

Niestety nie bardzo chce działać.
1) IP failover and virtual Mac address Let's consider your host public IP address is 91.123.123.123, and your guests public IP failover addresses are 91.2.2.2 (GUEST1) and 91.3.3.3 (GUEST2). >From your OVH Manager, assign a virtual Mac address to each of your IP failover. Select the "VMware type" ("OVH type" should also work, but I haven't yet tested). Let's assume your virtual Mac addresses for each IP failover are :
GUEST1: 91.2.2.2 <---> 00:50:56:0a:2a:aa
GUEST2: 91.3.3.3 <---> 00:50:56:0b:3b:bb
2) Host network configuration Then, set up your host network by editing the /etc/network/interfaces, and replacing the eth0 by a br0 interface.
Your file should look like this:
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo iface lo inet loopback
auto br0 iface br0 inet static
address 91.123.123.123
netmask 255.255.255.0
gateway 91.123.123.254
network 91.123.123.0
broadcast 91.123.123.255
bridge_ports eth0
bridge_stp off
bridge_maxwait 5
bridge_fd 0
Don't forget to restart your network (/etc/init.d/networking restart).
3) Guest configuration file Once your host network new configuration is up, edit the network part of your guest's configuration file (/var/lib/lxc/GUEST/config) with the IP failover and Mac adresses :
lxc.utsname = GUEST1
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
lxc.network.name = eth0
lxc.network.veth.pair = vethGUEST1
lxc.network.ipv4 = 91.2.2.2
lxc.network.hwaddr = 00:50:56:0a:2a:aa
And for GUEST2:
lxc.utsname = GUEST2
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
lxc.network.name = eth0
lxc.network.veth.pair = vethGUEST2
lxc.network.ipv4 = 91.3.3.3
lxc.network.hwaddr = 00:50:56:0b:3b:bb
4) Guest network configuration Then, add eth0 interface to your guest's /etc/network/interfaces file. The default gateway IP address should be the same as your host's one (for OVH servers, just replace the last byte of your host IP address by 254 (91.123.123.254 in my example) :
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 91.2.2.2
netmask 255.255.255.255
broadcast 91.2.2.2
post-up route add 91.123.123.254 dev eth0
post-up route add default gw 91.123.123.254
post-down route del 91.123.123.254 dev eth0
post-down route del default gw 91.123.123.254
That's it :-)
