I put this in /etc/sysconfig/openvswitch
BRCOMPAT=yes
Modules:
# lsmod|grep br
brcompat_mod 5873 0
openvswitch_mod 90652 1 brcompat_mod
On host I have eth2 that is configured on a physical switch in
trunking with vlan 65 and 66
I'm testing at the moment only the vlan65 functionality
Basic test config
# cat ifcfg-eth2
DEVICE=eth2
HWADDR=00:1C:C4:AB:3A:DD
ONBOOT=yes
BOOTPROTO=none
DEVICETYPE=ovs
TYPE=OVSPort
OVS_BRIDGE=brvlan65
OVS_OPTIONS="trunks=65,66"
NM_CONTROLLED=no
HOTPLUG=no
# cat ifcfg-brvlan65
DEVICE=brvlan65
DEVICETYPE=ovs
TYPE=OVSBridge
ONBOOT=yes
BOOTPROTO=static
STP=off
NM_CONTROLLED=no
HOTPLUG=no
OVS_EXTRA="br-set-external-id $DEVICE bridge-id $DEVICE"
after boot
# brctl show
bridge name bridge id STP enabled interfaces
