Description

After launching a VNF instance, if VM needs to be rebuild, we can rebuild a virtual machine if that is in error state to replace the virtual machine with an error-free virtual machine of the same name.

During Operations, for any reason, if VM is to be stopped or Started, VM Start/Stop feature would be helpful

VM Start-Stop-Rebuild feature will enable the user to start, stop and rebuild the VNF's virtual machines (VM) from osm's user action list.

Demo or definition of done

The following tasks should be completed:

• When VM in OpenStack goes to an error state, trigger the rebuild API with Ns instance id, Vm should be back active state with the same name.
• User can verify if the feature is done in two ways:
  • First by checking into the NS Instance "History Of Operation" where [Type: Rebuild, OprationStatus: Completed] should appear in UI.
  • Second after login into the VIM dashboard(Openstack) can see the status of the VM.
• VM Start-Stop-Rebuild feature developed and tested along with unit test cases

This work is considered done when the user is able to perform start stop rebuild using osm API or GUI from the user action list.
