It's bad luck for me not to boot with the 64 bit xen( which see its' 32 bit with "file")
my bootloader is gpxe.and don't see any output log, just see the target reboot

32 bit xen works well

The 64 bit hypervisor really is encapsulated in a 32 bit container, see
the mkelf32 related rules in xen/arch/x86/Makefile.

I'm not sure why. Something to do with 32 bit bootloaders maybe?
