Hi folks,
This is my first email here. Please let me know if there is any rule
or convention I need to follow. Don't want to break it.
I started with OpenStack Ussuri and OVN 20.03.0 recently and currently
running some scaling test. Searched around for scaling info and noticed
some improvements
nt OVN.
Any comment is welcome.
Thanks!

Hi,
The setup is OpenStack Ussuri and OVN 20.03.0.
After adding bunch of networks to a router via Neutron API, some of those
router interfaces
are "Active" and some of them are "Down". Is this expected?

In case of ovsdb cluster, when I run ovn-sbctl, it connects to the unix socket

Hi,
I see the active ovn-northd takes much CPU (30% - 100%) when there is no
configuration from OpenStack, nothing happening on all chassis nodes either.
Is this expected? What is it busy with?

Hi,
I have a few questions about ovn-northd HA.
Does the lock for active ovn-northd have to be acquired from the leader
of sb-db?
If ovn-northd didn't acquire the lock, it becomes standby. Does it keep
trying to acquire the lock, or wait for notification, or monitor the
active ovn-northd?
If it
does that sb-db leader switch affect such sync?

Hi,
Here is how I restore OVN DB.
* Stop all ovn-nb-db, ovn-sb-db and ovn-northd services.
* Clean up all DB files.
* Start all DB services. Fresh ovn-nb-db and ovn-sb-db clusters are up and
running.
* Set DB election timer to 10s.
* Restore DB to ovn-nb-db by ovsdb-client.
* Start all ovn-north
would restoring to a fresh cluster be better?
Is it necessary to stop or restart ovn-northd during DB restore?

Hi,
I wonder if we can have a solution combining all your excellent ideas?
* Don't clean up flows until recompute is done.
* Use nb_cfg to determine if update is required.
* Compute and apply the diff only.
* Save ovn-controller version in ovsdb.
Two scenarios to cover, restart and upgrade.

Hi,
Is there any version dependency between OVN and OVS,
like which OVS has to be used for certain OVN release?
Is such info shared anywhere?
Thanks!

Hi,
In http://www.openvswitch.org/support/dist-docs/ovn-architecture.7.html,
I see this.
For connecting to gateways, in addition to Geneve and STT, OVN
supports VXLAN, because only VXLAN support is common on
top-of-rack (ToR) switches.
Does anyone have experiences in using ph

Hi,
The ovsdb-server UNIX socket permission is 0750. It works
fine for OVS services, like ovs-vswitchd and ovn-controller
who run as root.
When integrate with OpenStack, neutron-ovn-metadata-agent
running as user "neutron" needs to connect to ovsdb-server.
TCP connection works fine. But, since it

Hi,
Could anyone share experiences in gateway routers scaling?
How many gateway routers on a chassis have be tested, hundreds,
thousands?
What may be the bottleneck for gateway router scaling, resources
like memory, CPU, or ovn-controller, OVSDB?
BTW, the link in ovn-architecture.7 is not valid a
Hi,
Here is what I did.

All resources are created in NB and translated to SB properly.

All resources are created and updated in NB properly, but SB
is not fully updated.

When I look at a datapath ingress pipeline,

That MAC is also in table 19.

Hi,
Given "Distributed Gateway Ports" in [1], and my test,
central SNAT, central FIP and distributed FIP are all supported by
distributed gateway port.
I wonder in which case gateway router has to be used?
One case is mentioned in [2], DR is used in K8S to support node
service and avoid central
Hi,
I am seeing an interesting issue today.
When ping a FIP from external, request arrives on GW, but no
tunnel from GW to compute.
When ping from VM to external, egress works fine, request
goes through tunnel from compute to GW, then to external.
Reply arrives at GW, no tunnel from GW back to com

Thanks!
Saw the same problem again. Recreate network, attach to router and
launch VM, problem is gone. Probably some glitch happened during
the early deployment. Any hints how to look into it?
Thanks!
