The following screenshot from cloud vm may explain you question.
You can see there is no ip address on eth0 when I lanch it from openstack dashboard.
Then I manually configure IP address and default gw:
ifconfig eth0 192.168.5.204 netmask 255.255.255.0
route add default gw 192.168.5.1
I can ping 192.168.5.0/24, but I can't ping 8.8.8.8

Also, what did you mean by this sentence?
"I relance an instance, but the problem is as before. how can i fix this? There is no error in log file."

I don't understand your topology now. If 192.168.5.0/24 has a floating IP on it, that means it's an external network and that you have some other external router on it. What is the device at the gateway IP of the 192.168.5.0 network?

So sorry, use neutron port-show, I find 192.168.5.207 is floating IP.
dhcp IP is 192.168.5.200,it is pingable
You know 192.168.5.208 is my cloud vm ip address. It is automaticaly configuer to vm os, I manually config it in the vm os. When I shutdown network on the cloud vm, I use port-show to see 192.168.5.208's state, it is the same as before.
I relance an instance, but the problem is as before. how can i fix this? There is no error in log file.

Name is just a field that can be set by users to track things.
Do a neutron port-show on e949854e-3533-48c5-8a1a-3dc455dfa59c to see the details of that DHCP agent port.

192.168.5.200 is provider network's start IP,192.168.5.203 is router IP, 192.168.5.208 is openstack vm instance IP, I configure it in vm os manually, they can ping from controller;
may be 192.168.5.207 is dhcp agent IP, I can't confirm this , and can't ping.
172.16 is self-service network
Why name field has no value? if 5.207 is dhcp agent ip and is not pingable, is this the root cause? how can i fix this

If you do a 'neutron port-list' do you see the DHCP agent port and is it ACTIVE?

I run dhcp agent on the controller, as the quick install doc suggest artechure. and I can see some port as follow
[root at controller ~]# netstat -tunlp | grep dh
udp 0 0 0.0.0.0:68 0.0.0.0:* 696/dhclient
udp 0 0 0.0.0.0:4407 0.0.0.0:* 696/dhclient
udp6 0 0 :::21133 :::* 696/dhclient
you mean: I lanch another vm not on openstack platform, set its ethernet proto to dhcp?

You need to run the DHCP agent on either the compute node or the same node running the L3 agent. It will get a port on the same network and offer DHCP addresses to the devices on that network.

Thank you kevin.
I just edit neutone code file and log nosise disapper.
As you say, the vm does not automate be configured ip address. But when I configure the address that openstack assign to it in the vm os, I can ping local network,but I can't
ping 8.8.8.8. On my physical server in the same local network , I can ping 8.8.8.8
And another tiny question, how can I get dhcp address, and can you give me some advice about which doc I can get experiencd with openstack's common command and case.

That bug just fixes the log noise. That was not the cause of the failure.
Check my suggestion about confirming that DHCP is working.

hi,kevin
From this link， I think you have fix this bug. But how can I use it in my environment?
Please forgive me, I'm newbie to openstack.
In my environment, I use centos7.3, and use yum to install openstack.

I believe that error is actually unrelated (bug reported here for that https://bugs.launchpad.net/neutron/+bug/1697383 ).
Do you have the DHCP agent running and is it's port active on the network? You should be able to ping the DHCP address from the 192.168.5 network.
If you don't have the DHCP agent, you will need to manually assign the IP in your instance.

My environment is:
two vms in virtualbox
each vm has two ethernet, 192.168.5.0/24 use bridge network; 10.0.0.0/24 use nat network, both is ok
I lanch provider network, and router ip is 192.168.5.203, I can ping it on the host.
openstack instance has got an ip,192.168.5.205, I can see it in network top0loy of the dashboard, and I can see provider network port is up,but I can't ping it.
