This works fine, it's just so slow. Of my 24 cores only 1 is used to compress the image. It could be so much faster. -- = 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.
