== Configuration d'un container (140) en virtual ethernet device (veth) ==

OBJECTIFS : A partir d'un serveur hôte équipé d'une carte ethernet multi-ports, installer des CTs publics et des privés sur des ports ethernet différents

=== création d'une interface eth1 sur le serveur hôte ===

# vi /etc/network/interfaces
{{{
allow-hotplug eth1
iface eth1 inet static
        address 10.72.1.3
        netmask 255.255.255.0
        network 10.72.1.0
        broadcast 10.72.1.255
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 10.72.1.2
        dns-search fr.auf
        up route add -net 10.72.0.0 netmask 255.255.0.0 gw 10.72.1.1
}}}

# ifup eth1

=== création du container 140 à partir d'un template ===

Le template doit contenir le paquet "iproute" installé

# vzctl create 140 --ostemplate debian-4.0-i386-minimal

# vzctl set 140 --netif_add eth1,00:80:C8:CD:67:6D,, --save 

# vzctl set 140 --nameserver 10.72.1.2 --save

# vzctl set 140 --hostname devel140 --save

=== configuration de la virtual ethernet device pour le container 140 ===

# ifconfig veth140.1 0

# echo 1 > /proc/sys/net/ipv4/conf/veth140.1/forwarding
 
# echo 1 > /proc/sys/net/ipv4/conf/veth140.1/proxy_arp
 
# echo 1 > /proc/sys/net/ipv4/conf/eth1/forwarding
 
# echo 1 > /proc/sys/net/ipv4/conf/eth1/proxy_arp 

=== configuration du container 140 ===

# vzctl start 140

# vzctl enter 140

# vi /etc/network/interfaces 
{{{
