systemd-vmspawn --bind-volume=PROVIDER:VOLUME[:CONFIG][:K=V,...] For each --bind-volume passed at startup, vmspawn calls Acquire() on the named StorageProvider and attaches the resulting fd to the VM as an additional drive. The drive is identified by the user-visible name '<provider>:<volume>' on the bridge — that is also the handle used later when machinectl unbind-volume detaches drives at runtime (though boot-time drives like these are NOT removable; that is the StorageImmutable behaviour added earlier). The colon grammar is parsed by the shared bind_volume_parse() helper. The 3rd 'config' field selects the guest device type from the disk_type_table[] vocabulary (virtio-blk, virtio-scsi, nvme, scsi-cd); empty defaults to virtio-blk per the TASK grammar. Wiring lives next to the existing --extra-drive setup: parse_argv() appends a parsed BindVolume to arg_bind_volumes, and prepare_device_info() hands the array to vmspawn_bind_volume_prepare_boot() which Acquires each volume and pushes a DriveInfo onto the existing drives array. PCIe port assignment (assign_pcie_ports()) and the QMP setup loop pick them up automatically. Signed-off-by: Christian Brauner (Amutable) <brauner@kernel.org>
