I have a the same problem. In systemd, there are two files openvswitch-nonetwork.service openvswitch-switch.service which are supposed to fix this problem
I am testing OpenStack with VXLAN and require sudo ovs-vsctl add-br br-eth2 sudo ovs-vsctl set port br-eth2 tag=2001 sudo ovs-vsctl add-port br-eth2 vxlan1 sudo ovs-vsctl set interface vxlan1 type=vxlan options:remote_ip=192.168.102.205 sudo ovs-vsctl add-port br-eth2 vxlan2 sudo ovs-vsctl set interface vxlan2 type=vxlan options:remote_ip=192.168.102.234 sudo ovs-vsctl add-br br-ex sudo ovs-vsctl add-port br-ex eth0 then bring up the network from /etc/network/interfaces with auto lo iface lo inet loopback auto eth0 iface eth0 inet manual up ifconfig $IFACE 0.0.0.0 up up ip link set $IFACE promisc on down ip link set $IFACE promisc off down ifconfig $IFACE down auto br-ex iface br-ex inet static address 192.168.102.206 netmask 255.255.255.0 gateway 192.168.102.36 dns-nameservers 192.168.102.10 192.168.102.50 up ip link set $IFACE promisc on down ip link set $IFACE promisc off auto br-eth2 iface br-eth2 inet static address 10.1.0.11 netmask 255.255.255.0 up ip link set $IFACE promisc on down ip link set $IFACE promisc off mtu 1446 from "sudo systemctl list-unit-files" i get openvswitch-nonetwork.service static openvswitch-switch.service enabled so I assume they are running -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1448254 Title: openvswitch systemd unit file ordering wrong To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1448254/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
