In linux kernel since version 5.2 (release Date: 2019-07-07)
Require virtio for Xen guests to use grant mappings.
This will avoid the need to give the backend the right to map all
of the guest memory. This will need support on the backend side
(e.g. qemu or kernel, depending on the virtio device types used).
