![]() We don't migrate the followings fields for virtio-pci: uint32_t dfselect; uint32_t gfselect; uint32_t guest_features[2]; struct { uint16_t num; bool enabled; uint32_t desc[2]; uint32_t avail[2]; uint32_t used[2]; } vqs[VIRTIO_QUEUE_MAX]; This will confuse driver if migrating during initialization. Solves this issue by: - introduce transport specific callbacks to load and store extra virtqueue states. - add a new subsection for virtio to migrate transport specific modern device state. - implement pci specific callbacks. - add a new property for virtio-pci for whether or not to migrate extra state. - compat the migration for 2.4 and elder machine types Cc: Michael S.
