I create simple patch :

diff --git a/tools/libxl/xl_cmdimpl.c b/tools/libxl/xl_cmdimpl.c
index a7f888c..6d87afe 100644
--- a/tools/libxl/xl_cmdimpl.c
+++ b/tools/libxl/xl_cmdimpl.c
@@ -3347,8 +3347,8 @@ static int migrate_read_fixedmessage(int fd,
const void *msg, int msgsz,
     if (rc) return ERROR_FAIL;

     if (memcmp(buf, msg, msgsz)) {
-        fprintf(stderr, "%s contained unexpected data instead of %s\n",
-                stream, what);
+        fprintf(stderr, "%s contained unexpected data instead of %s
buf %s msg %s\n",
+                stream, what, buf, (char*) msg);
         if (rune)
             fprintf(stderr, "(command run was: %s )\n", rune);
         return ERROR_FAIL;

I don't known does it need to be in xen repo?
