How to debug overlay network with solution linux-bridge+Vxlan from release liberty

Dears I am starting to install openstack of release liberty in my PC. And virtualbox is used to set up one computer node and one controller node with installation guide (centos) from office website now my problem is that the cirros of tenant can't get assigned ip from dhcp service. (there is no such problem for cirros in the public network). so I suspect that the bridge overlay-network may have some connections problems (since my controller and computer are also VMs in the software Virtualbox). so could someone share me how to debug this ?

thanks in advance

Steps to debug: Can you let us know the network configurations for your private network. This issue might not be happening in public network because of neutron dhcp able access it and able to assign IP. So you need to check how your OVS is configured. Few references: https://ask.openstack.org/en/question... http://docs.openstack.org/openstack-o...

thanks for your information, however, i don't use OVS, the docs of Liberty release indicates to use linux bridge+Vxlan http://docs.openstack.org/liberty/install-guide-rdo/ (http://docs.openstack.org/liberty/ins...), do i have to use OVS ?
