[PATCH 0/1] qemu: add virtio-blk queue-size option
Hello, The option "queue-size" in virtio-blk was added in qemu-2.12.0, and default value increased from qemu-5.0.0. However, increasing this value may lead to drop of random access performance. This is configurable value, so we want to use it via libvirt. Could you review this patch?
