Hello Alexey, 

> In order to enable IOMMU, add this to a virtio-pci device:

> -device virtio-blk-pci,iommu_platform=off,disable-modern=off,disable-
legacy=on

Does iommu_platform=off mean "enable IOMMU" ?

I was assuming that's the oposite during some tests I done in the past.

Best regards,
Leonardo
