Just like the restriction on sharing L2's, no guest is ever going to be able to not zero all of this to operate on older hypervisors. I agree that it is not ideal that this got into the ABI to begin with, but as I said before, all you are doing is complicating arch_set_info_guest() for a relaxation which no guest can use. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
