Regarding Openvswitch suppotrs Xen 4..2.1
Hi,
As I see blogs or websites the openvswitch is support XCP and Xenserver.
But to support opensource Xen 4.2.1 what should be configure and how to
interface with openflow .
I have tried using vif-openswitch network script for bridging, while
adding datapath using ovs-dpctl add-dp xenbr0 it is added but ovs-dpctl
dump-flows xenbr0 it is getting
ovs-dpctl: opening datapath (No such device). Can

Bug#679533: Traffic forwarding issue between Xen domU/dom0 and ovs
Package: xen-hypervisor-4.0-amd64
Version: 4.0.1-5.2
Hi,
We're seeing weird behaviour regarding network traffic between a Xen
dom0 and domU. I reported this issue yesterday to the
openvswitch-discuss mailing list, but it seems this could also be a
(regression?) bug in the xen hypervisor or the linux kernel... (we've
upgraded xen-hypervisor-4.0-amd64 4.0.1-4 -> 4.0.1-5.2 and

[ovs-discuss] OpenVswitch with KVM virtual machines
I am running NOX controller with a python script that prints out the
destination mac and the source mac for each packet arriving at the now
controller and then floods it out. So here's what happening:
With em1 connected, all the packets that arrive at em1 are coming to the
controller and printing out the details. However, without em1 connected to
the OVS, when I have the following setup:

Re: [ovs-discuss] create ovs port without root
The error that you're showing doesn't appear to be related to permissions; the "ovs-vsctl del-port" command requires that you specify the port that you want to delete.

Thanks for replying, I have downgraded libvirt back to version 5.6.0
(and VMs were again able to start), but I will try to reproduce the
problem on another machine in the next few days and post the logs here.
Thanks,

Ovs error when starting vm: ovs-vsctl: 'del-port' command requires at least 1 arguments
Hi,
my system got updated to libvirt 6.0.0 (from 5.6.0) this morning, and
now I'm having problems starting VMs that make use of openvswitch
portgroups.
When I start a VM, I get this error message on virsh:

I don't see any changes between 5.6.0 and now done to openvswitch in
libvirt (apart from harmless code reworks towards glib).

[XCP] XCP network and VLAN by Open vSwitch
Hello Everyone,
I am new with XCP.
I''ve setup several hosts with* XCP 1.0* and manage it through XenCenter and
command console.
Each host has two NICs, one (xenbr0) connected to a physical switch for
Internet (said sw1), the other (xenbr3) connected to a physical switch for
internal network (said sw2).
I am trying to setup VMs and VLANs on xenbr3.
I created a virtual bridge by

Does the bridge show up when you run "ovs-vsctl list-br"? Both OVS
bridges I have on my system are seen in that list. I created them both
with "ovs-vsctl add-br BLAH". How did you create your bridges?

facter fails to recognize OEL/OVS in operatingsystemrelease.rb
For the benefit of those running OEL (Oracle Enterprise Linux) or OVS,
be aware that under 2.6.0rc4 facter doesn''t properly recognize OEL in
/usr/lib/ruby/site_ruby/1.8/facter/operatingsystemrelease.rb. A diff
for a fix is below; probably not the best fix but if you need it work
now, this''ll do it for you.

problem with libvirt and ovs
Hello,
I have defined an ovs network with libvirt (virsh net-define ovs.xml) and created a vm that will connect to that network with virt-install. Although the vm port appears normally if i do an ovs-vsctl show, when i try to set this port as a mirror port for all the traffic in the bridge, the command is executed normaly, but then i cannot see any traffic on the interface.

Re: create ovs port without root
Thanks for answers,but as I see libvirt call ovs-vsctl that tries to

OVS+DPDK Problem
Hi All,
First time mailing here.
I have installed on a CentOS 7.0 KVM (with DPDK and OVS) one Deep Packet
Inspection VM.
I have one channel and some virtual traffic generator.
The traffic is lost between dpdk vhostuser and the DPI VM.
The setup is attached. Any suggestions or ideas?
Regarding the OVS+DPDK configuration, the following configuration is
already made:
- SELINUX is disabled
- QEMU
