These xm info, top, dmesg and log requre no parameter.
But log's error message differs from other 3 command's error messages,
when parameter is given.

# xm log 1
Error: 'xm log' requires 0 argument.

   log                              Print the xend log

Other 3 commands ignore parameter.
I think it might be better symmetricalize.
