Format "raw" doesn't always work on certain file systems (e.g. tmpfs). Use qcow2 to make the allocation status explicit and split into a new case. [Resolved merge conflict due to "qemu-io> " prompt filter, added 074 to group file, and fixed up s/048/074/ copy-paste mistake. --Stefan] Signed-off-by: Fam Zheng <famz@redhat.com> Reviewed-by: Wenchao Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
