Open Stack

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 at controller ~]# openstack network agent list

On the controller I got br-ex with a valid IP address. here is the
external-ids table on controller and compute node:

[root at 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 at 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:

I replaced valid IPs with X.X.X.X

Any suggestion would be grateful.
