Hi masters, I would install openstack kilo multi-node in SLE 12, and I have encountered problem when I prepare the settings for ovs. There two ifcfg needed for the openvswitch for the openstack br-ex using, ifcfg-br-ex, ifcfg-eth0(which to be used external int for VM instance). I set the /etc/sysconfig/network/ifcfg-br-ex follow the forum thread that can only one be found about ovs. # [https://forums.opensuse.org/showthread.php/497652-OpenVswitch-how-do-I-assign-ip-address-to-ovs-bridge](https://forums.opensuse.org/showthread.php/497652-OpenVswitch-how-do-I-assign-ip-address-to-ovs-bridge) BOOTPROTO=‘static’ BROADCAST=‘’ ETHTOOL\_OPTIONS=‘’ BRIDGE=‘yes’ BRIDGE\_PORTS= ‘eth0 br-ex’ IPADDR=‘192.168.2.51’ MTU=‘’ NAME=‘’ NETMASK=‘255.255.255.0’ NETWORK=‘’ REMOTE\_IPADDR=‘’ STARTMODE=‘hotplug’ #DHCLIENT\_SET\_DEFAULT\_ROUTE=‘yes’ ONBOOT=‘yes’ and set /etc/sysconfig/network/ifcfg-eth0 BOOTPROTO=‘none’ #BROADCAST=‘’ #ETHTOOL\_OPTIONS=‘’ #IPADDR=‘192.168.2.51’ #MTU=‘’ #NAME=‘’ #NETMASK=‘255.255.255.0’ #NETWORK=‘’ #REMOTE\_IPADDR=‘’ STARTMODE=‘auto’ #DHCLIENT\_SET\_DEFAULT\_ROUTE=‘yes’ #ONBOOT=‘yes’ But it not work after service network restart, can’t ping other IP in same subnet. I had tried another setting the official document provide, but not work too. # [https://en.opensuse.org/Portal:Wicked/OpenvSwitch](https://en.opensuse.org/Portal:Wicked/OpenvSwitch) I have some experience of openstack kilo deploying in RHEL(SL, Centos)7, but suse’s ifcfg-br-ex seems not like RHEL’s. Please help me to get the correct ifcfg, or give me some reference. We are extremely grateful for any reply. ---

Does no one install openstack/openvswitch in SLE 12? Please just share your ifcfg-br-ex and ifcfg-eth0(which port is ovs binded). ---

[/QUOTE] [SUSE Linux Enterprise Server](https://www.suse.com/products/server/) and [SUSE Linux Enterprise Desktop](https://www.suse.com/products/desktop/) are two different products.
