I want to test openstack on Dedicated server with OVH

[root@neutron ~]# ip netns
qdhcp-4468870e-3218-45d6-8811-14bf78b85b71
qdhcp-76629398-f33f-4811-845f-ebc1a69cac64
qrouter-0e7953fc-e40d-4795-a106-1b16b47acc3a

For demo subnet

[root@neutron ~]# ip netns exec qdhcp-76629398-f33f-4811-845f-ebc1a69cac64 ip a
11: tap8763a788-f6: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
