hello mukesh
      Now,I want debug the xen domU kernel or kernel modules, I found the tools gdbsx under xen source directory. As the guide of README you wrote, I compile the xen with: 
make gdbsx=y


but I got the errors as below:

could you give me some advice on how to solve this errors?
   thanks a lot.

This error message clearly indicates a problem building the kernel and
not gdbsx.

The fact that your kernel build tried to clone xen/master suggests you
are not building in an uptodate Xen source tree (it looks like you have
4.0.0). I recommend you use either the xen-4.0-testing.hg mercurial tree
or at a minimum update to the 4.0.1 release.

Since you only need to build the tools and not the kernels or hypervisor
you can use the tools targets as described in "make help". e.g.

 $ make gdbsx=y tools

(it looks like gdbsx=y is redundant since building gdbsx is not actually
optional, probably tools/debugger/gdbsx/README is out of date)

hi Ian
   As your suggestions, I compile the gdbsx tools independently use
   make gdbsx=y tools
   but when I executed the gdbsx on dom0, I got this error:
    ERROR:_check_hyp:Hyp is NOT enabled for gdbsx
    ERROR: failed to attach to domain:2 errno:38
   It looks like I have to recompile the xen & make it enable gdbsx.
       I just do like this: make gdbsx=y
   but I still get the error which I offered before.
   Should I use xen4.0.1? xen 4.0.0 not support gdbsx?
   our system using xen 4.0.0

Try adding "KERNELS=" to your make line, that will avoid the error
compiling the kernel.

I've no idea but as a general rule using the most recent stable release
is a good idea.

If you use xen-unstable, you don't need to build gdbsx by itself. It
is always built as part of the xen compilation.
After installing xen, it should end up in /usr/sbin/gdbsx on dom0.
