libxl: Remus - xl remus command
xl remus acts as a frontend to enable remus for a given domain.
* At the moment, only memory checkpointing and blackhole replication is
supported. Support for disk checkpointing and network buffering will
be added in future.
* Replication is done over ssh connection currently (like live migration
with xl). Future versions will have an option to use simple tcp socket
based replication channel (for both Remus & live migration).
