Hi,All.
    Recently I deploy an Openstack(Mitaka)+OVS(use VLAN isolation) in my lab,but I meet some problem.
Here is my package version:
[root at my1n12nt ~]# uname -r
3.10.0-514.26.2.el7.x86_64
[root at my1n12nt ~]# cat /etc/redhat-release 
CentOS Linux release 7.3.1611 (Core) 
[root at my1n12nt ~]# rpm -qa |grep openvswitch
openvswitch-2.6.1-4.1.git20161206.el7.x86_64
python-openvswitch-2.6.1-4.1.git20161206.el7.noarch
openstack-neutron-openvswitch-8.4.0-1.el7.noarch
[root at my1n12nt ~]# rpm -qa |grep openstack
openstack-neutron-common-8.4.0-1.el7.noarch
openstack-neutron-ml2-8.4.0-1.el7.noarch
openstack-neutron-8.4.0-1.el7.noarch
openstack-neutron-openvswitch-8.4.0-1.el7.noarch
openstack-neutron-fwaas-8.4.0-1.el7.noarch



When installed finish the Openstack is fine.Sometime the OVS will going fail.
