Re: [ovs-discuss] Issue with vlan tag being changed after reboot of KVM hypervisor

Hi Pippin, In general case, you can run an agent on the compute node. The agent can handle transactions sent by the controller node, when VMs destroyed/stopped/started. Then, the agent will set/unset the tag of VMs according to information which be sent by the controller. The VLAN of the

Re: [ovs-discuss] Issue with vlan tag being changed after reboot of KVM hypervisor.

Pippin, are you launching these VMs via libvirt? If so, most recent versions of libvirt have the ability to set the VLAN tag on the TAP interface that is created when you launch a VM. See here for more information: > On

That is an option, but if there is a way we can get these tags to persist it would be the best.   Regards – Pippin   From: Joel Wirāmu Pauling [mailto:aener...@aenertia.net] Sent: Thursday, May 19, 2016 1:28 PM To: Pippin Wallace Cc: nickcooper-zhangtonghao; discuss@openvswitch.org Subject:

[ovs-discuss] Instrumenting OVN

As I mentioned at today's IRC meeting - we have a need to include measuring the performance of the OVN control channel under scale as part of our CI/CD test suite, which is driving us to examine the feasibility of some sort of lightweight instrumentation of ovsdb-server, ovn-controller, and

[ovs-discuss] Question about "--monitor" option

ovs-vswitchd and ovsdb-server both support the --monitor option. According to the man page, --monitor creates an additional monitoring-process to monitor the daemon. How do we monitor the health of the monitoring-process itself? What if it crashes? Since there is no PID file configuration for

Re: [ovs-discuss] Collecting NetFlow data

I setup two fresh VMs assuming that something might be blocking, but still I'm getting the same logs. I'm also not getting any output on tcpdump for NetFlow port 2055. I've tried with changing the port as well. Please suggest how to proceed? 2016-05-19T19:51:13.874Z|00263|sflow|INFO|creating

Re: [ovs-discuss] Collecting NetFlow data

Hello Ben, Thanks for the prompt responses! The packets are being collected on the sFlow port 6343 at the same time, but giving unreachable error for NetFlow. This looks pretty awkward! Do you have some suggestions to further look into this matter? To tell you more about the setup, I'm using

Hello Ben, Thanks for the prompt response. Please have the output from the logs. Below are the logs related to collector, I'm not sure if its related to NetFlow collector or used in some other context. Kindly suggest further. *cat /var/log/openvswitch/ovs-vswitchd.log | grep collector*
