Centos 7 is not yet released so it's more easy to get patch in. I don't know what will be position when the guest is shipped. I bet they will still want to support 64KB with older Xen (i.e where 64KB grant is not supported). Anyway, I don't expect to see the 64KB grants support before next year as my TODO list is already pretty full. So let's talk about it when I (or someone else) will send an RFC to extend the grant size. Regards, -- Julien Grall
