Hi,
I have a use-case and I want to
(1) create vhost-user ports on OVS-DPDK running on a host
(2) in a container a dpdk-based application using virtio-user connecting to
vhost-user ports via sockets.
I looked at following 2 links from Intel which shows how-to configure
vhost-user and

- Move conntrack lock out of NAT module
- Use spinlock instead of read/write lock for conntrack entry.
- Update 'ctTotalRelatedEntries' using interlocked functions
- Refactor conntrack code to make it more readable.
Testing:
Evaluated TCP performance using iperf3.
Before optimization:

To review the problem we're trying to solve, ovn-controller uses too
much CPU in many circumstances because it recomputes everything on every
iteration on the main loop. That includes when it wakes up for any
reason, e.g. in response to a timer, or to an "ovs-appctl" command, or
to respond to an

I'm planning on reviewing this patchset, but when I applied the patch to

Add a test that performs typical operations of creating & destroying
logical routers, switches, ports, address sets and ACLs while checking
if they trigger full logical flow processing in the ovn-controller.
This way confirm that incremental processing is taking effect when we
expect it to.

Facilitate checking coverage counters from scripts and tests with a new
"coverage/read-counter" command that gets the total count for a counter.
Same could be achieved by scraping the output of "coverage/show" command
but the difficulties there are that output is in human readable format
and
(This patch set depends on v3 of the "ovn-controller incremental processing"
patch set [1].)
At the moment we lack tests that confirm that incremental logical flow
processing is working as expected. This patch set aims to address this.
The approach to testing is, in short, to observe if we hit

We have added new flows for using vlans instead of tunnels for
redirecting VLAN packets to a gateway chassis. This patch documents
these flows in ovn-northd.8.xml and ovn-architecture.7.xml.

External switches should learn the distributed gateway port MAC address
as they have to forward the packet tagged with tenant vlan network but
with this MAC as destination MAC address. So router has to send ARP

From: Venkata Anil
When a vm on a vlan tenant network sends traffic to an external network,
it is tunneled from host chassis to gateway chassis. In the earlier
discussion [1], Russel (also in his doc [2]) suggested if we can figure
out a way for OVN to do this redirect to the gateway host over a

This patch avoids tunneling and instead uses source tenant vlan network
across hypervisors for traffic from vlan network on local hypervisor
towards gateway hypervisor hosting redirect chassiss port.

Thanks for the additional tests. It might be nice to have one that tests
overlapping fragments, too. Also, it would be great if there could be IPv6
versions of these "corner cases".
Sorry it took so long to review these patches. I'll be faster on v7.
