Having the virtual IOMMU created with --iommu is one thing, but we also need a way to decide if a virtio-blk device should be attached to this virtual IOMMU or not. That's why we introduce an extra option "iommu" with the value "on" or "off". By default, the device is not attached, which means "iommu=off". One side effect of this new option is that we had to introduce a new option for the disk path, simply called "path=". Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>
