hi guys I have a qemu guest and openvswitch bridge and the guest fails to start: $ virsh start work8 error: Failed to start domain work8-vm-win2016 error: Cannot get interface MTU on 'ovsbr0': No such device LXC guest which uses the same source network starts just fine. I'm on Centos 7 with openvswitch-2.9.0-3.el7.x86_64 from centos-openstack-pike repo and libvirt-4.5.0-10.el7_6.7.x86_64. Would anybody care to suggest a possible reson(s) causing the failure? many thanks, L.

Hi , I have two virtual machines VM1 and VM2. Then I have added eth0 of my VM to 'default' network. Use case :- I want to monitor all traffic on virbr0('default' network). Steps followed :- 1. Add VM1 eth0 to virbr0 2. Add VM2 eth1 to virbr0 3. brctl setageing ovsbr0 0 ..(To put bridge in promiscuous) Now I am running tcpdump on eth1 of VM2 and trying to ping google.com(outside world) In VM2 (tcpdump -i eth1), I can see only ingress(incoming) traffic of VM1. I am not able see outgoing traffic of VM1. If I create another bridge and trying same scenario with 2...

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,

Is that so? Can you share your <interface/> configuration and the network XML? Michal

Hi, I have a machine with a Debian Stable installation that runs OpenVSwitch to connect a virtual machine on the same box. The machine is also running shorewall. The problem that I''m having is that shorewall try to run before openvswitch, this makes that shorewall fails because it can''t determine the IP of the virtual interface generated by openvswitch that start after

Good day gentlemen. I am building a study project and trying to configure openvswitch vlans outside libvirt by means of openvswitch itself. Somehow with interface types 'bridge' and 'network', libvirt does attach domain to the existing port specified in <target dev=''/>, wiping the exixting settings and always deletes this port upon domain shutdown, thus making me
