For an HVM domain, if a given pfn has a pagetype of XEN_DOMCTL_PFINFO_XTAB as returned by xc_map_foreign_batch(), does this mean that pfn is not not in the HVM guest's pseudo-physical map/have a valid P2M entry? I'm having difficulty understanding page types for HVM domains. If a pfn for an HVM domain is of the type XEN_DOMCTL_PFINFO_XTAB, can it later become a valid page? And what about the reverse case? Any help would be much appreciated, thanks, Mike _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
