I''m trying to do nested XEN to give some of my colleagues a play area to work in, and it seems to work - but not quite. I can build the nested environment (using OVM, and I have to step back to OVM3.2.2 to allow me to do PCI passthrough), but as soon as I start up a VM with a phys device passed through, the first layer loses all connectivity to the SAN. Setup: * 2 UCS

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. I''ve already filed a bug:

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

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!

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

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: > virsh # start testvm > error: Failed to start domain testvm > error: An error occurred, but the cause is unknown The system log contains: > Mar 30 09:45:39 tplinux

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, 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

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:

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?

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]:

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 ...
