I think this might actually be caused by a nasty bug in one of the previous patches (patch 27). I found it because every second time I launched a guest it failed. Strange, huh? These lines in drivers/lguest/page_tables.c: + pte_t ro_gpte = gpte; + pte_wrprotect(ro_gpte); Should be: + pte_t ro_gpte = pte_wrprotct(gpte); That's the only "break the host" issue I know of... Thanks!
