[ovs-dev] [PATCH v2] rhel: Prevent duplicate ifup calls.

[Denis Iskandarov]

After restarting network service.
"ovs-vsctl show" and "ovs-vsctl list-br" showing nothing - empty.
So nothing to delete. ifconfig -a not showing bridge as well.
system restart doesn't help.

My configs are:
DEVICE=br0
ONBOOT=yes
DEVICETYPE=ovs
TYPE=OVSBridge
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.0.111
NETMASK=255.255.255.0
HOTPLUG=no

DEVICE=eth0
ONBOOT=yes
DEVICETYPE=ovs
TYPE=OVSPort
OVS_BRIDGE=br0
NM_CONTROLLED=no
BOOTPROTO=none
HOTPLUG=no

DEVICE=eth1
ONBOOT=yes
DEVICETYPE=ovs
TYPE=OVSPort
OVS_BRIDGE=br0
NM_CONTROLLED=no
BOOTPROTO=none
HOTPLUG=no
