We would need the guest kernels to help out with reclamation (at least for guests not on shadow page tables). If Linux had support for hotplug memory (add and remove) I suspect we could make use of that to help out, if we were careful.Or simply get the balloon driver to target the appropriate pages. The problem with using hotplug memory is that that generally works on the basis of ranges of physical addresses, not machine addresses. Is there a VM interface to allow you to say 'please terminate usage of *that* page'? That could be extremely useful! -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
