Hi all, I've set up OpenStack Ussuri with OVN networking manually, VMs can ping each other through an internal network. I've created a provider network with valid IP subnet, and my problem is VMs don't have internet access before and after assigning floating IP. I've encountered the same problem on TripleO (with dvr), and I just wanted to investigate the problem by manual installation (without HA and DVR), but the same happened. Everything seems working properly, I can't see any error in logs, here is agent list output: [root@controller ~]# openstack network agent list +--------------------------------------+------------------------------+------------------------+-------------------+-------+-------+-------------------------------+ | ID | Agent Type | Host | Availability Zone | Alive | State | Binary | +--------------------------------------+------------------------------+------------------------+-------------------+-------+-------+-------------------------------+ | 1ade76ae-6caf-4942-8df3-e3bc39d2f12d | OVN Controller Gateway agent | controller.localdomain | n/a | :-) | UP | ovn-controller | | 484f123f-5935-44ce-aee7-4102271d9f11 | OVN Controller agent | compute.localdomain | n/a | :-) | UP | ovn-controller | | 01235c13-4f32-4c4f-8cf6-e4b8d59a438a | OVN Metadata agent | compute.localdomain | n/a | :-) | UP | networking-ovn-metadata-agent | +--------------------------------------+------------------------------+------------------------+-------------------+-------+-------+-------------------------------+ On the controller I got br-ex with a valid IP address. here is the external-ids table on controller and compute node: [root@controller ~]# ovs-vsctl get Open_vSwitch . external-ids {hostname=controller.localdomain, ovn-bridge=br-int, ovn-cms-options=enable-chassis-as-gw, ovn-encap-ip="10.0.0.11", ovn-encap-type=geneve, ovn-remote="tcp:10.0.0.11:6642", rundir="/var/run/openvswitch", system-id="1ade76ae-6caf-4942-8df3-e3bc39d2f12d"} [root@compute ~]# ovs-vsctl get Open_vSwitch . external-ids {hostname=compute.localdomain, ovn-bridge=br-int, ovn-encap-ip="10.0.0.31", ovn-encap-type=geneve, ovn-remote="tcp:10.0.0.11:6642", rundir="/var/run/openvswitch", system-id="484f123f-5935-44ce-aee7-4102271d9f11"} and I have: [root@controller ~]# ovn-nbctl show switch 72fd5c08-6852-4d7e-b9b4-7e0a1ccdd976 (neutron-b8c66c3d-f47a-42a5-bd2d-c40c435c0376) (aka net01) port cf99f43b-0a18-4b91-9ca5-b6ed3f86d994 type: localport addresses: ["fa:16:3e:d0:df:82 192.168.0.100"] port 4268f511-bee3-4da0-8835-b9a8664101c4 addresses: ["fa:16:3e:35:f2:02 192.168.0.135"] port 846919e8-cde5-4ba3-b003-0c06e73676ed type: router router-port: lrp-846919e8-cde5-4ba3-b003-0c06e73676ed switch bb22224e-e1d1-4bb2-b57e-1058e9fc33a7 (neutron-9614546f-b216-4554-9bfe-e8d6bb11d927) (aka provider) port 2f05c7bc-ad0f-4a41-bbd8-5fef1f5bfd2c type: localport addresses: ["fa:16:3e:17:7b:5b X.X.X.X"] port provnet-9614546f-b216-4554-9bfe-e8d6bb11d927 type: localnet addresses: ["unknown"] port 23fcdc9d-2d11-40c9-881e-c78e871a3314 type: router router-port: lrp-23fcdc9d-2d11-40c9-881e-c78e871a3314 router 0bd35585-b0a3-4c8f-b71b-cb87c9fad060 (neutron-8cdcd0d2-752c-4130-87bb-d2b7af803ec9) (aka router01) port lrp-846919e8-cde5-4ba3-b003-0c06e73676ed mac: "fa:16:3e:4d:c3:f9" networks: ["192.168.0.1/24"] port lrp-23fcdc9d-2d11-40c9-881e-c78e871a3314 mac: "fa:16:3e:94:89:8e" networks: ["X.X.X.X/22"] gateway chassis: [1ade76ae-6caf-4942-8df3-e3bc39d2f12d 484f123f-5935-44ce-aee7-4102271d9f11] nat 8ef6167a-bc28-4caf-8af5-d0bf12a62545 external ip: " X.X.X.X " logical ip: "192.168.0.135" type: "dnat_and_snat" nat ba32ab93-3d2b-4199-b634-802f0f438338 external ip: " X.X.X.X " logical ip: "192.168.0.0/24" type: "snat" I replaced valid IPs with X.X.X.X Any suggestion would be grateful.
