Xen users - Feb 2009 - [Xen-API] How does "xm save & restore" are executed in the source code?

Hi all,
      I''m reading the code about "xm save & restore".
Every xm commands execution start in the python file
"tools/python/xen/xm/main.py ", but I am puzzled where the xenapi are
implemented? for example:

if serverType == SERVER_XEN_API:       
        server.xenapi.VM.save(get_single_vm(dom), savefile, checkpoint)
    else:
        server.xend.domain.save(dom, savefile, checkpoint)

what are the invoking sequence about "server.xenapi.VM.save" and
"server.xend.domain.save" ?  which file are they implemented? I also
search the python-C interfaces about "xm save & restore" in
"tools/python/xen/lowlevel/xc/xc.c", but failed to find out the
"pyxc_domain_save" or "pyxc_domain_restore" ?
     
Best Regards
