Hi, I was wondering, perhaps in my ignorance, what prevents an auto-translated-physmap linux guest from being suspended/resumed. As far as I understand, there would be no need for pagetable canonicalization code in xc_linux_save, as well as no need for those mfn_to_pfn translations in pre_suspend (and viceversa in post_suspend) Anything I am missing? Thanks! Andres _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Since auto-translated-physmap is typically only used by various research projects its not particularly well maintained, but its usually easy to fix up.
