Xen_create_contiguous_region() gives up the existing RAM and replaces with a new contiguous extent, so it shouldn't allocate net extra memory. How are you determining amount of RAM used: xm info and looking at freemem? Or xm list and look at memory usage for dom0? -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
