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 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?
