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: Code: # 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?
