Hi masters,

I would install openstack kilo multi-node in SLE 12, and I have encountered problem when I prepare the settings for ovs in Network node.

There are two ifcfg modification needed for the openvswitch for the openstack external netwoking using,  
ifcfg-br-ex, ifcfg-eth0(which nic to be used external for VM instance).

I set the /etc/sysconfig/network/ifcfg-br-ex follow the forum thread that can only one be found about ovs.

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, I think it is because of missing part parameters.

And also search in mailing list of ovs official site, no solution found.

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 share the correct ifcfg setting, or some reference.

We are extremely grateful for any reply.
