That was also my feeling, so nice to get a confirmation! Another related thing would be to allow qemu-nbd to write compressed blocks its backing image - today if you use a qcow2 with compression, any block which is written to gets uncompressed in the resulting image and you need to recompress the image offline with qemu-img.
Would you have any pointers/documentation on how best to implement this so both qemu-img and qemu-nbd can use multithreaded compressed writes ? I'm totally new to qemu block subsystem. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/601946 Title: [Feature request] qemu-img multi-threaded compressed image conversion Status in QEMU: New Bug description: Feature request: qemu-img multi-threaded compressed image conversion Suppose I want to convert raw image to compressed qcow2. Multi- threaded conversion will be much faster, because bottleneck is compressing data. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/601946/+subscriptions
