After VM was created. According to qemu-img info, the disk size is 0. # qemu-img info /rhev/data-center/mnt/blockSD/eaa6f641-6b36-4c1d-bf99-6ba77df3156f/images/8d3b455b-1da4-49f3-ba57-8cda64aa9dc9/949fa315-3934-4038-85f2-08aec52c1e2b image: /rhev/data-center/mnt/blockSD/eaa6f641-6b36-4c1d-bf99-6ba77df3156f/images/8d3b455b-1da4-49f3-ba57-8cda64aa9dc9/949fa315-3934-4038-85f2-08aec52c1e2b file format: raw virtual size: 10G (10737418240 bytes) disk size: 0 I tried on iscsi and same result. Is the behaviour expected? It is expected in a way. Disk size is the amount of storage actually used, and block devices has no way to tell that. oVirt report the size of the block device in this case, which is more accurate than zero. However the real size allocated on the undrelying storage is somewhere between zero an device size, and depends on the imlementation of the storage. Nither qemu-img nor oVirt can tell the real size.
