Open Stack

Folks,

I need some advice or suggestion to find out what is going on with my
network, we have notice high packet loss on openstack instance and not
sure what is going on, same time if i check on host machine and it has
zero packet loss.. this is what i did for test...

ping 8.8.8.8

from instance: 50% packet loss
from compute host: 0% packet loss

I have disabled TSO/GSO/SG setting on physical compute node but still
getting packet loss.

We have 10G NIC on our network, look like something related to tap
interface setting..
