or
c/s b154537ad07598377ebf98252fb7d2aff127983b
moved the testing of xen_enabled() from pc_init1() to
pc_machine_initfn().
xen_enabled() does not return the correct value in
pc_machine_initfn().
Changed vmport from a bool to an enum. Added the value "auto" to do
the old way. Move check of xen_enabled() back to pc_init1().

When we dynamically modify boot order, the length of
boot order will be changed, but we don't update
s->files->f[i].size with new length. This casuse
seabios read a wrong vale of qemu cfg file about
bootorder.
