The first patch adds QEMU replies and as such has been aggressively
snipped to deal with mailing list message size limits. Grab the
unabriged version with

 $ git fetch https://gitlab.com/abologna/libvirt.git virtio-iommu


As noted in patch 10, the QEMU feature this series enables has not
yet been accepted upstream: the relevant patches are

 https://lists.gnu.org/archive/html/qemu-devel/2021-10/msg00161.html
 https://lists.gnu.org/archive/html/qemu-devel/2021-09/msg07819.html

and of course this series should only be merged once those have gone
in.

That said, patches 1-6 are necessary to implement the feature but
also not strictly related to it, so they could be merged right away.


Changes from [v1]:

 * rebased after Peter's recent changes enabling JSON for -device.
