Because of different layouts and sizes of certain structures for 32-bit versus 64-bit guests, save/restore/migrate currently only works where the domU is the same 'bitness' as your dom0. This restriction does not apply to HVM domUs, only PV domUs. We hope to lift the restriction for Xen 3.1.1. 32-on-64 is one of the 'harder' new features in 3.1.0, so it will take a little while to beat out the last few bugs and feature regressions! -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
