Maybe you can give me some hints: on amd64 arch, i'd like to know about hypervisor callback: ie, stack layout when called by Xen, stack location in memory (is it using the TSS entry as hardware traps do?) and finally, about how HYPERVISOR_iret() expects to find the stack upon call (like when you used iret? or something else?). I may write a little paper or tutorial from i've learned and didn't found in Xen doc after i get a better view of the whole thing... Regards, Mathieu
