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 all , i use ubuntu 12.04 with xcp , all config run very well except vlan i use xe network-create and xe vlan-create to build vlan 3000 then startup a vm in this network, xapi0 fakebridge and vif1.0 all looks well, use ovs-vsctl list port i can see xapi0 and vif1.0 have beed taged with 3000 but i can not access the internent~~~ somebody can help me with this? thanks.

Hi, I have two systems(a laptop and a desktop) connected with an Ethernet cable. Desktop is using the Internet through the laptop wireless LAN. Both systems have Ubuntu 11.10 with XEN 4.1.2 Hypervisor. I have compiled OpenvSwitch-1.5 on both the systems as well. In Linux Bridge mode both can ping each other. Problem: LINUX bridge is used in both systems and both can access the internet but as

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]:

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, 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,

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 all, im peter, i found the post here http://www.gossamer-threads.com/lists/xen/users/229738 i build a small test env, with 2 vm in 1 server with xcp 1.1.0 i use xe network-create and xe vlan-create to build the vlan for each vm. then i got 2 bridge like xapi1 and xapi2, and in the ovs-vsctl list port i can see all these info about fake-bridge and vlan tag is correct. but when i start 2

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

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?

Based on Waldi''s RFC at http://lists.xen.org/archives/html/xen-devel/2012-09/msg00943.html To use it set vif.default.script="vif-openvswitch" in /etc/xen/xl.conf or use script=vif-openvswitch in the vif configuration. Appears to do the right thing for PV and HVM guests (including tap devices) and with stubdomains. In order to support VLAN tagging and trunking the

I can see from different post that if working with sr-iov, i should work with vlan Is this an obligation to work with vlan if working with sr-iov? If not according to which parameter will the different vf get the traffic. Let's say i declare max_vfs=7, how will the traffic be seperated between the vm? However till i get an answer i tried to work with vlan And i still don't get

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:
