Well, it's hard to know, since your description doesn't describe your topology,
configuration, etc. That said, I guess I would start with tcpdump or flow
counts to see where packets appear to be getting dropped and why.

Hi all.
I am setting up a network node for the OpenStack cluster (mitaka) in the
classic scenario with OpenvSwitch (
https://docs.openstack.org/liberty/networking-guide/scenario-classic-ovs.html#openstack-services-network-node).
On the network node a neutron is launched. The neutron controls the

Hi team OvS and OVN!
As a huge fan of OVN and Dustin’s blog series, I’ve just wrote Ansible
playbooks to make the Dustin’s OVN primer in action as on the github

Thank you, Dustin and team OVN, again to make this cool stuff happening
and get going

I am using ovs on a Fedora 20 KVM Host with 6 defined vlans
I am having a problem where when I stop any VM I lose connectivity to all other
VM's for about 6-7 Pings.
Then everything starts working again.
Anyone see this or know a remedy for it?
Thanks,
Dean Price

Hi Aaron
Thanks
I see there are 2 approaches as mentioned by you
1. Regarding the first I assume u mean creating another netns and creating
peers between ethwan1 and veth1
Say we have another netns lying outside ovs whose one interface (say veth1
lying inside netns test) is linked to ovs internal

hi all:
I am going to implement the meter speed limit. I read the book of
"ovs-ofctl.pdf " about the instructions of burst. In this pdf book , the
instructions of burst is : If multiple bands' rate is exceeded,then the band
with the highest rate among the exceeded bands is selected . It's a
Hi All,
I need to capture all received SYN packets from all interfaces and to
mirror/output to a specific interface in addition to the operational interface
that these packets should be forwarded.
Can I do it with a single dpctl add-flow cli command ? and not modify the
'operational' flows tha
I found this article very relevant to this issue:
http://porto.polito.it/2616822/1/2015_Chain_performance.pdf
especially it says that for the vhost-net interface used for standard OVS:
"the transmission of a batch of packets
from a VM causes a VM exit; this means that the CPU stops to execute
