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. --Justin On Mar 6, 2014, at 2:05 AM, Vasiliy Tolstov <v.tolstov@selfip.ru> wrote: > Hello!

Thanks for answers,but as I see libvirt call ovs-vsctl that tries to connect to ovs-vswitchd socket,that have rw to root.how can I specify socket permissions in vswitchd?

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

Hello! How can i operate with openvswitch without root rights? For example - i can add my user to kvm group and create vm from libvirt with my own user, but now i'm failed with creating port. errors in logs: Mar 06 14:04:46 selfip.ru ovs-vsctl[19065]: ovs|00001|vsctl|INFO|Called as ovs-vsctl --timeout=5 -- --if-exists del-port Mar 06 14:04:46 selfip.ru ovs-vsctl[19065]:

After some digging in openvswitch code. My wild guess is that vlan tag reconfiguring triggered iface_configure_qos (vswitchd/bridge.c), which in turn called netdev_set_policing to reset ingress policing rate. Although there's no ingress_policing_rate set in my case, existing ingress qdisc still remove by default. Could some openvswitch guy help to confirm and suggest how to fix or workaround?

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:

With outbound QoS setting in Libvirt XML, libvirt will add a tc ingress qdisc for traffic shaping. Then if you set VLAN tag to that tap device, this qdisc will automatically gone by no reason. Could anyone shed some lights where should I look into? I'm really confused and got no clue here. Thanks! Steps to reproduce -- # virsh start instance-name # virsh dumpxml instance-name ...

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. Could you give me

Hi, I have an existing OVS bridge, that I can see in ovs-vsctl and use for other purposes. I've edited the machine's XML as instructed in http://docs.openvswitch.org/en/latest/howto/libvirt/ When I try to start the VM, i get error: Cannot get interface MTU on 'ovsbr': No such device Any ideas? (Note: I can't see the ovs switch in brctl show or any other regular kernel tool,

Hi list, I'm using OVS as backend for guest networking on my hypervisors. VLAN configuration for each interface is specified into the guest XML definition. When I need to change VLAN configuration of a running guest, I first edit the inactive XML to keep the changes for future boots, then I use ovs-vsctl to instruct the changes on the existing OVS Port. The problem happen when the guest is

I have installed OVS from sources using the installation steps mentioned on this link: http://docs.openvswitch.org/en/latest/intro/install/general/ I had installed libvrt, KVM, QEMU and all the necessary packages using apt-get. My KVM-QEMU hypervisor has been running well. To add a VM with the port attached to OVS bridge I changed the XML domain file as per the instructions on this page:

Hi, I have created a libvirt network on top of a OVS bridge (named vlan-br) which receives all VLAN tagged packets, i.e. connected to a trunk port. The definition xml is below. What I want to achieve in the portgroup definition 'trunk-native-1221' is to allow 1221 as untagged/native but rest all VLAN as tagged. The following portgroup definition works, but I don't want to enumerate
