+## construct_virtio_dev {#rpc_construct_virtio_dev}
+
+Create new initiator @ref bdev_config_virtio_scsi or @ref bdev_config_virtio_blk and expose all found bdevs.
+
+### Parameters
+
+Name                    | Optional | Type        | Description
+----------------------- | -------- | ----------- | -----------
+name                    | Required | string      | Virtio SCSI base bdev name or Virtio Blk bdev name
+trtype                  | Required | string      | Virtio target trtype: pci or user
+traddr                  | Required | string      | target address: BDF or UNIX socket file path
+dev_type                | Required | string      | Virtio device type: blk or scsi
+vq_count                | Optional | number      | Number of queues this controller will utilize (default: 1)
+vq_size                 | Optional | number      | Size of each queue. Must be power of 2. (default: 512)
+
+In case of Virtio SCSI the `name` parameter will be base name for new created bdevs. For Virtio Blk `name` will be the
+name of created bdev.
+
+`vq_count` and `vq_size` parameters are valid only if `trtype` is `user`.
+
+### Result
+
+Array of names of newly created bdevs.

+## construct_virtio_user_scsi_bdev {#rpc_construct_virtio_user_scsi_bdev}
+
+This is legacy RPC method. It is equivalent of @ref rpc_construct_virtio_dev with `trtype` set to `user` and `dev_type` set to `scsi`.
+
+Because it will be deprecated soon it is intentionally undocumented.
+
+
+## construct_virtio_pci_scsi_bdev {#rpc_construct_virtio_pci_scsi_bdev}
+
+This is legacy RPC method. It is equivalent of @ref rpc_construct_virtio_dev with `trtype` set to `pci` and `dev_type` set to `scsi`.
+
+Because it will be deprecated soon it is intentionally undocumented.
+
+## construct_virtio_user_blk_bdev {#rpc_construct_virtio_user_blk_bdev}
