I think it would help to compare your proposal with the alternative of adding grant table infrastructure to such environments (which I wouldn't expect to be all that difficult). After all introduction of a (seemingly) redundant mechanism comes at the price of extra / duplicate code in the tool stack and maybe even in the hypervisor. Hence there needs to be a meaningfully higher gain than price here. Jan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
