Keir,
thank you very much.
now I'm using the un-stable version to build hvmloader (only hvmloader
rebuild, xen and doman0 kernel is not touched), the same problem.
(XEN) HVM1: Trap (0x6) while in real mode

(XEN) HVM1:
(XEN) HVM1: Halt called from %eip 0xD037C
here is some snip from objdump, and i attach the whole objdump as the
