In linux kernel since version 4.19.310 (release Date: 2024-03-15)
This provides migration support for VIRTIO NET PCI VF devices
using the VFIO framework. Migration support requires the
SR-IOV PF device to support specific VIRTIO extensions,
otherwise this driver provides no additional functionality
beyond vfio-pci.
Migration support in this driver relies on dirty page tracking
provided by the IOMMU hardware and exposed through IOMMUFD, any
other use cases are dis-recommended.
