Oh , here before i run 
                  1)     ./configure --with-xen=/usr/include/xen/     &&  
                  2)     make && make install 
 i had run automake/autoconf tool , and the errors still like what i got .
So how to fix it ?

Oh , I know that, maybe i didn't express the right meaning . Now , i am more
clearer . Yes , what i want to detect is the Xen toolstack's memory leak not
the hypervisor itself . 

and so suppose that i come to the third step, is it right to use the command
to do the detection ?
"valgrind --tool=memcheck --leak-check=yes xm" 


and more does someone have the valgrind tool support for hypervisor well ,
can you send me one ?

Thank you and best wishes .
