Review request for cloudstack.


Changes
-------

created the bugfix CLOUDSTACK-599 on jira and updates this summary tab for this bugfix


Description
-------

Identified and resolved issue for Router VM on vSphere 5.0 and CS 4.0 - where a router VM
would come up however the Link Local IP would be unreachable until you initiate a ping request
from Router VM itself. As the result - you are unable to deploy instances. The logs display
a problem with DhcpEntryCommand as Router VM is unreachable. The router VM does not receive
inbound communication, but outbound communication is fine.
The ping updates the ARP table with additional MAC entry of the gateway. We are ping the gateway
of CS host specifically - as this is the major needed source of communication. Once ARP table
is updated - communication works in both directions.  


This addresses bug CLOUDSTACK-599.
