The intel-iommu device has existed since QEMU 2.2.0, but it was only possible to create it with -device since QEMU 2.7.0, thanks to: commit 621d983a1f9051f4cfc3f402569b46b77d8449fc Author: Marcel Apfelbaum <marcel@xxxxxxxxxx> Date: Mon Jun 27 18:38:34 2016 +0300 hw/iommu: enable iommu with -device Use the standard '-device intel-iommu' to create the IOMMU device. The legacy '-machine,iommu=on' can still be used. The libvirt capability check & command line formatting code is thus broken for all QEMU versions 2.2.0 -> 2.6.0 inclusive. This fixes it to use iommu=on instead. Signed-off-by: Daniel P.
