Public bug reported:
Hi
I am using Open vSwitch/ML2 for neutron and creating a flat network as the
provider.
I have created two instances on the same compute node with the flat network.
When using tcpdump on one instance, I can watch the unicast traffic of another
instance, and it is so weird!!!
Port security is enabled, and the security group is also configured.
Even if I remove all security groups and use tcpdump from the instance's
console, I can watch other unicast traffic.
