Title:
  the tap interface created on network node - doesn't accept packets

Status in OpenStack Neutron (virtual network service):
  Expired

Bug description:
  An instance newly created, cannot access network (in and out); cannot
  be sshed into neither can be pinged. Only console works!

  Analysis:
  -------------
  the instance cannot be pinged from the network node, but the network node can ping the DNS by itself.

  [A] Ping from an outside server to the instance: 
  After listening on to the interface that the instance is associated on (tap-interface) on that node, we can see that the interface does receive the packets sent in. but it doesn't transmit the packets from their on to the instance itself.

  Solution:
  -------------
  "service neutron-openvswitch-agent restart"  doesn't resolve the problem and the instance' network start working, only for sometime, until the bug kicks in.
