I'm seeing up to 30 threads per virtual disk, which seems high. In case it's related, the block devices are iSCSI with the host acting as the initiator and exposing block devices to qemu. I'm particularly interested in qemu 2.2, just in case things have changed significantly since then. Thanks, Chris
