openstack juno with NetworkManager

Post by woa » 2015/01/30 05:31:02

Q: Can openstack juno run with NetworkManager together?

Some Notes:
I'm running openstack (juno) cloud on CentOS 7(release 7.0.1406). The cloud physical network use openvswitch plugin and system physical NIC is managed by NetworkManager service. When i deploy my vm, openstack will create bridge and virtrual ports(qbr*,qvb*,qvo*,tap*). I found NetworkManager can auto configure these ports and get IP address by DHCP(external DHCP server). How to let it do not manage these ports? When i delete my vm and use nmcli command to delete the connection, the NetworkManager service become failed.

Steps To Reproduce:
1 systemctl status network;systemctl status NetworkManager; #Confirmation of these services is working.
2 brctl addbr br-test; #add a testing bridge
3 nmcli conn show | grep br-test; # show br-test connection, you can find this connection.
4 ifconfig br-test down;brctl delbr br-test; # delete br-test bridge.
5 nmcli conn show | grep br-test; # show br-test connection, you can still find this connection.
6 nmcli conn delete br-test; systemctl status NetworkManager; # you can see NetworkManager service failed.
