Murali Reddy updated CLOUDSTACK-7191:
-------------------------------------
Description:
RestartNetwork is implemented with below logical steps
- clean up network rules on the provider (implemented by
shutdownNetworkResources)
- shutdown the providers for the network
- implement all providers for the network
- reprogram the rules
step #1 is unnecessary in case the provider is appliance based like virtual
router. so at present even for the VR significant amount of time is consumed to
clean up the rules. This step is unnecessary as appliance will get destroyed
any ways in next step.
During upgrades in an environments with large number of networks with VR as the
only provider, it will take significant time.
This bug should ensure cleanup of rules is done only if required.
