4. A metadata preallocated qcow2 file: 14.5 seconds qemu-img create -f qcow2 -o preallocated=metadata test.img 300M
Just tested this on a F13 host, and it didn't like the the preallocated option: $ qemu-img create -f qcow2 -o preallocated=metadata testvm.qcow2 20G Unknown option 'preallocated' qemu-img: Invalid options for file format 'qcow2'. $ Looks like we'd need to add some kind of testing for the capability first. :)
