OpenvSwitch setup

[snoopel]

Hi @all,

Iam a new user of proxmox. I want to configure a OpenvSwitch Setup in a new proxmox installation. I have to network-interface (eth0, eth1), I want to configure these interface as active/backup bonding. I installed the openvswitch-switch package and create a new device over the GUI of proxmox. My currently interfaces looks like this:

# network interface settings
auto lo
iface lo inet loopback

allow-vmbr1 eth1
iface eth1 inet manual
        ovs_type OVSPort
        ovs_bridge vmbr1

allow-vmbr1 eth0
iface eth0 inet manual
        ovs_type OVSPort
        ovs_bridge vmbr1

allow-vmbr1 bond0
iface bond0 inet manual
        ovs_type OVSBond
        ovs_bridge vmbr1
        ovs_bonds eth0 eth1
        ovs_options bond_mode=active-backup

iface vmbr0 inet manual
        bridge_ports none
        bridge_stp off
        bridge_fd 0

auto vmbr1
iface vmbr1 inet static
        address  192.168.0.22
        netmask  255.255.255.0
        gateway  192.168.0.1
        ovs_type OVSBridge
        ovs_ports bond0

proxmox does not find vmbr1. What is wrong?

do you have reboot your host after update the /etc/network/interfaces ?

also, can you send the result of the command:

"ovs-vsctl show"

Hey spirit,

yes, I do a reboot after configuration. Now, I do the openvswitch configuration manually, ovs-vsctl add-br and ovs-vsctl add-bond.

root@myserv:~# ovs-vsctl show
01b0ff45-01e2-4b28-85d5-bc91b916e04d
    Bridge "vmbr1"
        Port "vmbr1"
            Interface "vmbr1"
                type: internal
        Port "bond0"
            Interface "eth0"
            Interface "eth1"
    ovs_version: "1.4.2"
root@myserv:~#

but the slave interfaces or bond0 interface won't be started. I can do ifup vmbr1 and ifconfig eth0 up and the vmbr1 will be working. A pure setup by the proxmox gui do not working for me!

Try to use classic configuration for ethX interface (as you use bonding, ethX are not managed by openvswitch)

# network interface settings
auto lo
iface lo inet loopback


auto eth1
iface eth1 inet manual


auto eth0
iface eth0 inet manual


allow-vmbr1 bond0
iface bond0 inet manual
        ovs_type OVSBond
        ovs_bridge vmbr1
        ovs_bonds eth0 eth1
        ovs_options bond_mode=active-backup




auto vmbr1
iface vmbr1 inet static
        address  192.168.0.22
        netmask  255.255.255.0
        gateway  192.168.0.1
        ovs_type OVSBridge
        ovs_ports bond0
