Hi,

When wrong options are given to xm save, I'd like to show the usage 
message of xm save as follows.

# xm save --hogehoge vm1 /tmp/vm1.save
Error: option --hogehoge not recognized
Usage: xm save [-c] <Domain> <CheckpointFile>

Save a domain state to restore later.
  -c, --checkpoint               Leave domain running after creating
                                 snapshot


Signed-off-by: Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>

Best regards,
 Kan
