nstead pass flags to the virStorageVolDownload/Upload functions, eg VIR_STORAGE_VOL_STREAM_COMPRESS_ZLIB. This flag would get passed across to the storage driver, which can then turn on compression in the virFDStream impl. This would require
- Add the enum flags to include/libvirt/libvirt-storage.h - Add libarchive support to src/fdstream.c - Handle the new flags in src/storage/storage_driver.c to turn on the libarchive compression in fdsream.c
I have a problems with enabling compression in fdstream. In my case use pass flag to VolDownload, in storage_driver i don't have ability to access privateData of the stream, so i need to create additional variable in stream struct ? Or i miss something? Also does the same stream can be used to read and write in the same time? (libarchive need to init own structure for read or for write) -- Vasiliy Tolstov, e-mail: v.tolstov@selfip.ru
