Does Xen use the start_info (passed in ctxt->esi) for anything (such as setting up CR3), or is this value just passed on to the domain? Is passing bogus start_info a problem for Xen? If not, what is the state of CR3 and paging when the domain boots? best, Jacob ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
