====== Openvswitch ======
{{tag>virtualisation libvirt openvswitch}}

===== Installation =====
Nous installons les paquets
<code>
aptitude install openvswitch-switch
</code>

===== Configuration =====
Nous adaptons le fichier /etc/network/interfaces pour qu'il ressemble à ceci
<code>
auto lo
iface lo inet loopback

auto vmbr0
allow-ovs ovsbr0
iface vmbr0 inet manual
        ovs_type OVSBridge
        ovs_ports eth0 vlan40 vlan41
	mtu 9000

allow-ovsbr0 eth0
iface eth0 inet manual
	ovs_type OVSPort
	ovs_bridge ovsbr0
	ovs_options tag=40 vlan_mode=native-untagged
	mtu 9000

allow-ovsbr0 vlan40
iface vlan40 inet static
	ovs_type OVSIntPort
	ovs_bridge ovsbr0
	ovs_options tag=40
	ovs_extra set interface ${IFACE} external-ids:iface-id=$(hostname -s)-${IFACE}-vif
	address 192.168.40.241
	netmask 255.255.255.0
	gateway 192.168.40.1
	mtu 1500

allow-ovsbr0 vlan41
iface vlan41 inet static
        ovs_type OVSIntPort
        ovs_bridge ovsbr0
        ovs_options tag=41
        ovs_extra set interface ${IFACE} external-ids:iface-id=$(hostname -s)-${IFACE}-vif
        address 192.168.41.241
