[ovs-discuss] Tag lost after network restart

Thu Nov 12 03:02:16 UTC 2015

By the way, I just saw some one with the same situation:
http://website-humblec.rhcloud.com/configure-openvswitch-in-virt-environment/
search with 'lost' you'll see that comment.

And he used Ubuntu, so this problem is platform irrelevant. I'm guessing
misconfiguration now. But I don't know where I did wrong. Here are my
ifcfgs:

ifcfg-bond0:
DEVICE=bond0
ONBOOT=yes
BOOTPROTO=none
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=ovsbr0

ifcfg-ovsbr0:
IPADDR=10.3.150.20
NETMASK=255.255.255.0
DEVICE=ovsbr0
TYPE=OVSBridge
DEVICETYPE=ovs
ONBOOT=yes
BOOT_PROTO=static
