VFIO migration is not compatible with postcopy migration. A VFIO device in the destination can't handle page faults for pages that have not been sent yet. Doing such migration will cause the VM to crash in the destination: qemu-system-x86_64: VFIO_MAP_DMA failed: Bad address qemu-system-x86_64: vfio_dma_map(0x55a28c7659d0, 0xc0000, 0xb000, 0x7f1b11a00000) = -14 (Bad address) qemu: hardware error: vfio: DMA mapping failed, unable to continue To prevent this, block VFIO migration with postcopy migration.
