iotests: Test convert to qcow2 compressed to NBD Add test for "qemu-img convert -O qcow2 -c" to NBD target. The tests     create a OVA file and write compressed qcow2 disk content directly into the OVA file via qemu-nbd.

iotest 302: use img_info_log() helper Instead of qemu_img_log("info", ..) use generic helper img_info_log(). img_info_log() has smarter logic. For example it use filter_img_info() to filter output, which in turns filter a compression type. So it will help us in future when we implement a possibility to use zstd compression by default (with help of some runtime config file or maybe build option). For now to test you should recompile qemu with a small addition into block/qcow2.c before "if (qcow2_opts->has_compression_type": if (!qcow2_opts->has_compression_type && version >= 3) { qcow2_opts->has_compression_type = true; qcow2_opts->compression_type = QCOW2_COMPRESSION_TYPE_ZSTD; } Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Reviewed-by: Max Reitz <mreitz@redhat.com> Message-Id: <20211223160144.1097696-12-vsementsov@virtuozzo.com> Signed-off-by: Hanna Reitz <hreitz@redhat.com>

qcow2: Add the 'extended_l2' option and the QCOW2_INCOMPAT_EXTL2 bit Now that the implementation of subclusters is complete we can finally add the necessary options to create and read images with this feature, which we call "extended L2 entries".
