Hi ,
Thank you very very much, you can ask any questions.
> If I understand well you have a single host all-in-one setup, am I right?<
Yes, you are right.
> You mentioned flat network, for that please check this document to be sure that you have everything set correctly:
> https://docs.openstack.org/neutron/latest/admin/deploy-ovs-provider.html
I have configured and recreated the network and instances according to this document. But the network behaves the same and still has no DHCP response. All settings is in line with this document, except the single host only have one nic, so I put all network in it, such as Management network adn Provider network.
If you need any information, I will provider it soon.
paste more details information in here:

Han Guangyu
