Add a --iommu option to configure IOMMU parameters as described in https://libvirt.org/formatdomain.html#elementsIommu E.g. 'virt-install --iommu model=intel,driver.aw_bits=48,driver.iotlb=on ...' will generate the following domain XML: <devices> <iommu model="intel"> <driver aw_bits="48" iotlb="on"/> </iommu> </devices> Reviewed-by: Cole Robinson <crobinso@redhat.com> Signed-off-by: Menno Lageman <menno.lageman@oracle.com>
