Bug description:
When boot a VM with nova network, it always report " NovaException:
Failed to add interface: device br100 is a bridge device itself; can't
enslave a bridge device to a bridge device." and this caused my VM can
not be started.
Reproduce steps:
1) Install OpenStack with Devstack
jay@jay001:~/src/devstack$ cat localrc
HOST_IP=192.168.0.103
ADMIN_PASSWORD=nova
MYSQL_PASSWORD=nova
RABBIT_PASSWORD=nova
SERVICE_PASSWORD=nova
SERVICE_TOKEN=tokentoken
FLAT_INTERFACE=br100
#VIRT_DRIVER=docker
#RECLONE=yes
VERBOSE=True
LOG_COLOR=True
SCREEN_LOGDIR=/opt/stack/logs
#disable_service horizon
#OFFLINE=False
