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 VM then VM2 can see both ingress and outgress traffic. So want to know what is the issue? Is libvirt doing something different with this virtbr0 bridge? -- Sagar Dilip Shedge, Pune. With Regards. -- Sagar Dilip Shedge, Pune. With Regards.
