Quoting from : " * 4. This the order of bootstrap elements in the initial virtual region: * a. relocated kernel image * b. initial ram disk [mod_start, mod_len] * c. list of allocated page frames [mfn_list, nr_pages] * d. bootstrap page tables [pt_base, CR3 (x86)] * e. start_info_t structure [register ESI (x86)] * f. bootstrap stack [register ESP (x86)]" But when i run my domU kernel (homemade), i found myself with start_info struct BETWEEN pt_base and end of page tables (pt_base + (nr_pt_frames << PAGE_SHIFT). Is it intended? Regards, Mathieu
