There's a May 11 post from Aaron Roberts saying: I'm guessing you're using qemu-kvm? If so, qemu-kvm will use O_SYNC (cache=writethough) to open a raw disk image and O_DIRECT (cache=none) to open a .qcow2 image. Would it then be accurate to say that fuse and qemu are currently compatible for raw kvm images, but not for qcow2 images? If so, that would explain why it's been working okay in my instance. I use raw images, which are said to be faster, if lacking qcow2 features like internal snapshotting. Whit
