If no specific destination groups are specified using ``--to``, all
groups except the evacuated group are considered.
The moves of the individual instances are handled as separate jobs
to allow for maximal parallelism. If the ``--sequential`` option is
given, the moves of the individual instances will be executed sequentially.
This can be usefull if the link between the groups is vulnerable to
congestion.
See **ganeti**\(7) for a description of ``--submit`` and other common
options.
