OK, to expand on your answer a bit, the difference is that the HTAB is allocated from the Xen heap, while the RMA is allocated from the domain heap. We have to free all domain heap memory in domain_relinquish_resources(), and only then will domain_destroy() be called. I think it might make sense to allocate the HTAB from the domain heap instead, but it's working for now... -- Hollis Blanchard IBM Linux Technology Center _______________________________________________ Xen-ppc-devel mailing list Xenemail@example.com http://lists.xensource.com/xen-ppc-devel
