No. Pages are expected to be cleared by a guest when it frees them if it cares about secrecy. Also Xen will clear pages that belong to a guest when a guest dies (since the guest is no longer around to do it for itself). But a guest cannot assume pages it allocates are zeroed. -- Keir On 29/11/06 08:40, "Li, Xin B" <xin.b.li@intel.com> wrote:> thanks > -Xin > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
