KVMFORNFV: Reverting LiveMigration changes

This patch consists of reverting the changes of patch 45227 and
incudes redirecting the console output of the LiveMigration
execution to /dev/null as the stdout contains only the statistics,
i.e., totaltime, downtime and setuptime.

This reverts commit 5a1f65d3e7d67488ee6f558dccfa5ca5581ddb65.
