Alex Williamson 3f68b0318b KVM: IOMMU: Disable device assignment without interrupt remapping ... IOMMU interrupt remapping support provides a further layer of isolation for device assignment by preventing arbitrary interrupt block DMA writes by a malicious guest from reaching the host. By default, we should require that the platform provides interrupt remapping support, with an opt-in mechanism for existing behavior. Both AMD IOMMU and Intel VT-d2 hardware support interrupt remapping, however we currently only have software support on the Intel side. Users wishing to re-enable device assignment when interrupt remapping is not supported on the platform can use the "allow_unsafe_assigned_interrupts=1" module option.
