For backward compatibility I placed the IDENT_PT location in a new ‘chunk’ 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@xxxxxxxxx> wrote: The patch save/restore the HVM_PARAM_IDENT_PT parameter, then the live migration during real mode with EPT may work fine. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
