Oh, you're talking about qemu-iotests/check already supporting merely '-valgrind', not 'qemu-kvm' or '*/qemu-system-*'. ./check is already an oddball for not permitting double dash, but at this point, normalizing it is a lot of churn. So it becomes a tradeoff on how much grunt work do you really want to do. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org
