Hi Reza,

Here is a related bug: 

https://bugs.launchpad.net/bugs/1881041

I had to use ovn/ovs 2.13 builds from cbs to overcome this issue (

https://cbs.centos.org/koji/buildinfo?buildID=30482)

Regards,

Michal

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

21:13:06.808900 ARP, Request who-has dns.google tell 

X.X.X.X

X.X.X.X if FIP of VM.

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

Do you suggest installing ovn manually from source on containers?

Hi,





Maybe You hit this bug [1]. Please check what ovn version do You have and maybe


update it if needed.
