Hi, Keir, Sorry for the xsave-introduced regression bug. I have fixed and attached the patch with this email. xsave-migration.patch contains all the changes you have reverted plus the fix I made. xsave-migration-fix.patch only contains the fix I made based on original xsave patch series. I have tested the patch in the following senarios: 1> Non-xsave platform 2> Xsave-capable platform, guest does not support xsave, xen support xsave 3> Xsave-capable platform, guest does support xsave, xen supports xsave 4> Guest (non-xsave) saved on platform without xsave, restored on a Xsave-capable system. All passed. Could please have review? Thanks! Again, sorry for the regression caused. Signed-off-by: Shan Haitao <haitao.shan@xxxxxxxxx> Signed-off-by: Han Weidong <weidong.han@xxxxxxxxx> Shan Haitao
