By "where" i mean the physical address, not the machine address. I didn't found the answer in the docs, but i have some ideas: - at physical 0x100000 (1 MB) - at physical 0x0 (unlikely) - at (kernel_virtual_entry - kernel_virtual_base) Any of thoses? Somewhere else? Likewise, i'm looking for the virtual base offset (ie, virtual address of physical address 0x0). I guess it's at VIRT_BASE when you specify in the xen_guest section, but what if you don't? Regards, Mathieu
