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
