Hello,
The openvswitch version on master seems to be wiping out the bridge's IP
when openvswitch gets restarted and it is only after restarting network
services that the IP comes back.
I'm using commit 6872bf1eb7e46f9c202d512aa5ca6d99fe35d23e
I've also verified that I don' see this issue with versions 2.3.1 and 2.4.0
Here are the network-scripts I have:
# cat ifcfg-enp0s9
DEVICE=enp0s9
ONBOOT=yes
DEVICETYPE=ovs
TYPE=OVSPort
OVS_BRIDGE=br-ex
BOOTPROTO=none
HOTPLUG=no
# cat ifcfg-br-ex
DEVICE=br-ex
ONBOOT=yes
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=static
IPADDR=192.168.2.103
NETMASK=255.255.255.0
HOTPLUG=no
