Symptoms

Connectivity to oda_base VM in the form of ssh or application to oda_base gets stalled for few seconds.

The ping test shows packet loss for few seconds and then works fine. This pattern repeats frequently.

There will be no issue with connectivity between application VMs.

If we capture multiple sessions of tcpdump data simultaneously on Dom0 at the same time when ping test is also done we can see that the packets are wrongly sent to bond0 instead of oda_base.

To do this get the "brctl show" output from Dom0 and capture tcpdump for <vif_app>, <vif_oda_base> and <bond_interface>
