An instance was created with IP address IP1 using cloudify API. Later on a network port was created using neutron with IP address IP2. The newly created interface is then assigned to the instance. I am able to ping instance with IP1 but not IP2. Both IPS belongs to same subnet.

Verified that interfaces are configured correct from within the guest. I am able to ping using both IPs from with-in the guest.

when you create a neutron port, if you don't assign a security group, neutron will use the "default" security group, and usually the default security group only permit all on egress and nothing on ingress, so check your instances security group.
