Which feature do you think can be improved?

When create a kata Pod, I want to pass iommu_platform=on for supported device in qemu, so that I can take advantage of the IOMMU feature. Details of IOMMU can be found in https://wiki.qemu.org/Features/VT-d

How can it be improved?

I'd like to add a new annotation like EnableDeviceIOMMU = kataAnnotHypervisorPrefix + "enable_device_iommu" and a new knobs like DeviceIOMMU in qemu, so that I can append the iommu option for all supported devices.

Additional Information

Anything else to add?
