*Hello,* I have installed Xen as Hypervisor with OpenSUSE running in Dom0. I want to use ovswitch (ovs) instead of the bridges that Xen created. In order to do so, I installed ovs in dom0 just like for the plain Linux. Xen has replaced eth0 with peth0, and has created a bridge named eth0. And eth0 is connected peth0 interface , vif2.0 interface (VM), and everything is working fine. Now I delete

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?

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]:

Hi. I'd like to use Openvswitch while running libvirt as an unprivileged user (qemu:///session). As expected, system session works just fine with OVS. When I try to start the domain from user session, with the relevant network part of the domain xml edited to use openvswitch, like this --- <interface type='bridge'> <mac address='52:54:00:4a:ef:bb'/>

Hey folks, I'm working on setting up a Cuckoo sandbox malware lab at home, and can't seem to get openvswitch and libvirt to work together as-documented. I'm not subscribed to the list, so please reply-all. Thanks in advance! I've debugged this, and I think the interfaceid stuff in network XML isn't doing much besides setting a custom interfaceid in an OpenVSwitch table that

Howdy, Running the most recent OVS and libvirt I'm running into the following error message with virt-install: root at qemu-kvm:~/libvirt-1.0.5#<mailto:root at qemu-kvm:~/libvirt-1.0.5#> ovs-vsctl -V ovs-vsctl (Open vSwitch) 1.11.90 Compiled May 6 2013 22:37:22 root at qemu-kvm:~/libvirt-1.0.5#<mailto:root at qemu-kvm:~/libvirt-1.0.5#> root at

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 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

Hey, I have KVM installed on my Fedora 17 box. I added the network interfaces of the virtual machines to the openvswitch bridge as follows: ____ ____ / VM1\______br0_______/ em1\ \____/ | \____/ | _|_ /VM2\ \____/ virbr0 is the virtual network switch VM1 and VM2 are on the same subnet having tap interfaces vnet0 and vnet1 respectively. em1 is the default

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,

In general if no MTU is set on interface creation the default value is 1500. On OVS the bridge MTU is automatically set to the smallest port MTU. So you just have to set the MTU of each port of the bridge. Take a look at: https://bugzilla.redhat.com/show_bug.cgi?id=1160897 It is a bit of a pain to read but seems to confirm the statement about the OVS MTU value being set by the MTU of the

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 ...

Hi everyone, I'm forwarding this mail that I wrote to OpenVSwitch dev list because I think that you could maybe help me a little :-) What did you think about the patch to libvirt that I'm using?. At least, it worked for me :-) Thanks. Ernesto ---------- Forwarded message ---------- From: Ernesto Domato <edomat at gmail.com> Date: Mon, Mar 4, 2013 at 2:09 PM Subject: OpenVSwitch

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).
