Hi, all: I disable Rich formatting in gmail, does the format looks good now? To tinnycloud: hvm_hap_nested_page_fault() will be called when a guest writes a shared page. 2011/1/11 MaoXiaoyun <tinnycloud@xxxxxxxxxxx> > > Hi Tim: > > Sorry for the inconvenience, I think it's better now when I reply > directly from hotmail. > > It looks like when unshare(), page_set_owner is forgetten, right? Inside unshare(), it does the following (1) page_make_private() --> page_set_owner(page, d) to update page_info structure. So there is no need for you to add page_set_owner explicitly. (2) set_shared_p2m_entry() to update the page table >From your log file, the page_make_private() is not called/executed properly. Could you debug into it also?
