Hi all! These series makes all test pass with
IMGOPTS='compression_type=zstd' Also, python iotests start to support IMGOPTS (they didn't before). Also, tests works if enable compression type zstd by default. There is no such config option currently, probably it will appear in future or we'll go some another way (like external config file, like /etc/qemu.conf). For now you may test with a simple patch like: --- a/block/qcow2.c +++ b/block/qcow2.c @@ -3539,6 +3539,11 @@ qcow2_co_create(BlockdevCreateOptions *create_options, Error **errp) goto out; } } + + if (!qcow2_opts->has_compression_type && version >= 3) { + qcow2_opts->has_compression_type = true; + qcow2_opts->compression_type = QCOW2_COMPRESSION_TYPE_ZSTD; + } if (qcow2_opts->has_compression_type && qcow2_opts->compression_type != QCOW2_COMPRESSION_TYPE_ZLIB) { We want to use zstd compression type by default in Virtuozzo 8. This is the first step, which is good anyway: improve iotests.
