Honestly speaking it loads partially.
Now I got new error message
(XEN) elf_init: not an EL binary
...
Panic on CPU 0
I tried Xen 3.2.1 and Xen 3.4.
Unfortunately I do not have right CPU on my testing PC.
I think it's old Pentium without VT support.
Hope to find in google related advices and will try it.
Also I will try to find something more modern than my old PC to make full test.
Anyway I have to say that previously reported error message (Early fatal page fault) gone in i386.
Thank you.
