Transcribing one of your images: > pahome@pahome-QW09:~/git/qemu/build$ ./qemu-img --help > qemu-img version 2.9.0 (v2.9.0-dirty) You aren't building the latest version of qemu.git. If you were, you'd be getting something like this: $ ./qemu-img --help | head -n1 qemu-img version 2.9.50 (v2.9.0-2519-gb52f59694d) Before you can complain that something recently added isn't working, you first have to make sure you are building the right version. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
