Hi Roman, I'm using 'geneve' for my tenant networks. By the way, by pinging 8.8.8.8 from an instance with FIP, tcpdump on its Compute node shows an ARP request for every lost ping. Is it normal behaviour? 21:13:04.808508 ARP, Request who-has dns.google tell X.X.X.X , length 28 21:13:05.808726 ARP, Request who-has dns.google tell X.X.X.X , length 28 21:13:06.808900 ARP, Request who-has dns.google tell X.X.X.X , length 28 . . . X.X.X.X if FIP of VM. On Tue, 8 Sep 2020 at 17:21, Roman Safronov <rsafrono@redhat.com> wrote:
Hi Reza,
Are you using 'geneve' tenant networks or 'vlan' ones? I am asking because with VLAN we have the following DVR issue [1]

Hi Slawek,
I'm using the latest CentOS 8 Ussuri OVN packages at: https://trunk.rdoproject.org/centos8-ussuri/deps/latest/x86_64/
On both Controller and Compute I get:
# rpm -qa | grep ovn ovn-host-20.03.0-4.el8.x86_64 ovn-20.03.0-4.el8.x86_64
# yum info ovn Installed Packages Name : ovn Version : 20.03.0 Release : 4.el8 Architecture : x86_64 Size : 12 M Source : ovn-20.03.0-4.el8.src.rpm Repository : @System From repo : delorean-ussuri-testing Summary : Open Virtual Network support URL : http://www.openvswitch.org/ License : ASL 2.0 and LGPLv2+ and SISSL
Do you suggest installing ovn manually from source on containers? ي

Hi,
Maybe You hit this bug [1]. Please check what ovn version do You have and maybe update it if needed.
Hi all,
I deployed an environment with TripleO Ussuri with 3 HA Controllers and some Compute nodes with neutron-ovn-dvr-ha.yaml Instances have Internet access through routers with SNAT traffic (in

case traffic is routed via a controller node), and by assigning IP address directly from provider network (not having a router).
But in case of assigning FIP from provider to an instance, VM Internet connection is lost. Here is the output of router nat lists, which seems OK:
# ovn-nbctl lr-nat-list 587182a4-4d6b-41b0-9fd8-4c1be58811b0 TYPE EXTERNAL_IP EXTERNAL_PORT LOGICAL_IP EXTERNAL_MAC LOGICAL_PORT dnat_and_snat X.X.X.X 192.168.0.153 fa:16:3e:0a:86:4d e65bd8e9-5f95-4eb2-a316-97e86fbdb9b6 snat Y.Y.Y.Y 192.168.0.0/24
I replaced FIP with X.X.X.X and router IP with Y.Y.Y.Y
When I remove * EXTERNAL_MAC* and *LOGICAL_PORT*, FIP works fine and as it has to be, but traffic routes from a Controller node and it won't be distributed anymore.
Any idea or suggestion would be grateful. Regards, Reza
