====================================

Checking the code I found this in LibvirtComputingResource:

boolean shrinkOk = cmd.getShrinkOk();

} else if (type.equals("QCOW2") && shrinkOk) {
    return new ResizeVolumeAnswer(cmd, false, "Unable to shrink volumes of type " + type);
}

Seems like a logical mistake? Shouldn't that be !shrinkOk?

Wido
