qemu-img is going to switch the default for QCOW2 to QCOW2v3 (compat=1.1) [0]
Extend the probing for qemu-img command line options to check if -o compat is supported. If the volume definition specifies the qcow2 format but no compat level and -o compat is supported, specify -o compat=0.10 to create a QCOW2v2 image.
https://bugzilla.redhat.com/show_bug.cgi?id=997977 --- [0] the switch is not yet upstream. The proposed (incomplete) QEMU patch: http://lists.nongnu.org/archive/html/qemu-devel/2013-08/msg02549.html
ACK, Incidentally, it sucks that while we've solved the capabilities detection problem for QEMU avoiding the need to use -help or similar args, we now re-introduce the problem for qemu-img.
