The vmdk disk can be created with -o subformat=monolithicFlat
option. A flat disk image fills unused space. Doc: qemu-img create

What's the best way to create a fixed size disk with qemu-img ? I tried doing this., and it always seems to be creating a virtual /growing disk, doing a ls returns the actual small size of the vmdk.
is there a way to create a "fixed size" disk?
root@local:/tmp# qemu-img create -f vmdk test.vmdk 2G Formatting 'test.vmdk', fmt=vmdk size=2147483648 compat6=off zeroed_grain=off root@local:/tmp# qemu-img info test.vmdk image: test.vmdk file format: vmdk virtual size: 2.0G (2147483648 bytes) disk size: 12K root@local:/tmp# ls -lah test.vmdk -rw-r--r-- 1 root root 320K May 13 09:15 test.vmdk

some user over 2 yearsWhile the answer by user319088 checked out, I want to comment that if other user come here looking for way to create a fixed size, native .qcow2 image, I have not found a way. Even converting from flat vmdk does not work.
