[GENIUS-234] the vxlan tunnel disappear after deleting the vms on the compute node

The netvirt configure file is :

{odl_dir}/etc/opendaylight/datastore/initial/config/genius-itm-config.xml ：

<def-tz-enabled>false</def-tz-enabled>

<gpe-extension-enabled>true</gpe-extension-enabled>
{odl_dir}

/etc/opendaylight/datastore/initial/config/netvirt-elanmanager-config.xml ：

<auto-config-transport-zones>true</auto-config-transport-zones>

<use-of-tunnels>true</use-of-tunnels>

1、So the vxlan tunnels are created after the vm is booted first on the compute node. like this：

[root@computer1-r ~]# ovs-vsctl show

c40586c2-afe7-4be9-87e0-3405fbcc2ae4

Manager "tcp:192.168.100.13:6640"

is_connected: true

Bridge br-int

Controller "tcp:192.168.100.13:6653"

is_connected: true

fail_mode: secure

Port "tun1593f6a7311"

Interface "tun1593f6a7311"

type: vxlan

options: {exts=gpe, key=flow, local_ip="192.168.100.31", remote_ip=flow}

Port "tap6087d304-05"

Interface "tap6087d304-05"

Port br-int

Interface br-int

type: internal

ovs_version: "2.9.0"

2、Then I delete the vm on the compute ,I found the vxlan tunnel is deleted. like :

[root@computer1-r ~]# ovs-vsctl show

c40586c2-afe7-4be9-87e0-3405fbcc2ae4

Manager "tcp:192.168.100.13:6640"

is_connected: true

Bridge br-int

Controller "tcp:192.168.100.13:6653"

is_connected: true

fail_mode: secure

Port br-int

Interface br-int

type: internal

ovs_version: "2.9.0"

3、Last I created a new vm on the compute node ,I found the vm was created successfully but the vxlan tunnels was not created:

c40586c2-afe7-4be9-87e0-3405fbcc2ae4

Manager "tcp:192.168.100.13:6640"

is_connected: true

Bridge br-int

Controller "tcp:192.168.100.13:6653"

is_connected: true

fail_mode: secure

Port "tap2a22261c-d4"

Interface "tap2a22261c-d4"

Port br-int

Interface br-int

type: internal

ovs_version: "2.9.0"

The log follow the link:

4、I restart the odl ,and the tunnel was recreated again.
