Users can attach such a qcow2 file to the guest as a zoned device. To create a qcow2 file with zoned format, use command like this: $ qemu-img create -f qcow2 test.qcow2 -o size=768M -o zone_size=64M -o zone_capacity=64M -o zone_nr_conv=0 -o max_append_sectors=512 -o max_open_zones=0 -o max_active_zones=0 -o zoned_profile=zbc Then add it to the QEMU command line: -blockdev node-name=drive1,driver=qcow2,file.driver=file,file.filename=../qemu/test.qcow2 \ -device virtio-blk-pci,drive=drive1 \ Sam Li (4): docs/qcow2: add the zoned format feature qcow2: add configurations for zoned format extension qcow2: add zoned emulation capability iotests: test the zoned format feature for qcow2 file block/qcow2.c | 746 ++++++++++++++++++++++- block/qcow2.h | 23 + docs/system/qemu-block-drivers.rst.inc | 31 + include/block/block-common.h | 5 + include/block/block_int-common.h | 8 + qapi/block-core.json | 46 +- tests/qemu-iotests/tests/zoned-qcow2 | 110 ++++ tests/qemu-iotests/tests/zoned-qcow2.out | 87 +++ 8 files changed, 1041 insertions(+), 15 deletions(-) create mode 100755 tests/qemu-iotests/tests/zoned-qcow2 create mode 100644 tests/qemu-iotests/tests/zoned-qcow2.out
