Re: [Xen-devel][PATCH][EPT] Fix the realmode live migration issue with EPT
For backward compatibility I placed the IDENT_PT location in a new chunk¹ in the save/restore format. Please see changeset 17849. I also removed the code you added in xc_domain_restore.c to re-initialise the ident_pt page. It should be saved/restored along with all other guest memory, so this re-initialisation ought to be unnecessary. You might want to test that this is indeed the case. -- Keir On 13/6/08 09:32, "Xin, Xiaohui" <xiaohui.xin@intel.com> wrote:> The patch save/restore the HVM_PARAM_IDENT_PT parameter, then the live > migration during real mode with EPT may work fine. > > Signed-off-by: Xin, Xiaohui<Xiaohui.xin@intel.com> > > > > _______________________________________________ > 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
