Changes the flags to read only and then write the page table entry back (shadow_set_l1e). When going through the page table, I can use SHADOW_FOREACH_L1E (L2E, L3E, L4E) macro. However, I have one question. When dealing with shadow page table L2, L3, L4, can I use the same way as L1 page table to change flags and set flags ? } } Do you think my idea is possible? Th...

Hi, --- background ---------------------------------------------------- * what the makedumpfile is: To shorten the size of the dumpfile and the time of creating the dumpfile, makedumpfile copies only the necessary pages for analysis to the dumpfile from /proc/vmcore.

We (Michael Fetterman, George Dunlap and I) have been working over the last while on a full replacement for Xen''s shadow pagetable support. This mail contains some design notes, below; a patch against xen-unstable, giving a snapshot of the current state of the new shadow code, is at http://www.cl.cam.ac.uk/~tjd21/shadow2.patch Comments on both are welcome, although the code is not
