How to do it...

Perform the following steps to create a blank raw image of a specified size and to verify that the file was created on the host:

  1. Create a raw image named debian.img with size of 10 GB:
root@kvm:~# qemu-img create -f raw debian.img 10G    
Formatting 'debian.img', fmt=raw size=10737418240
root@kvm:~#
  1. Check that the file was created:
root@kvm:~# ls -lah debian.img    
-rw-r--r-- 1 root root 10G Feb 10 16:58 debian.img
root@kvm:~#
  1. Examine the file type:
root@kvm:~# file -s debian.img    
debian.img: data
root@kvm:~#
  1. Obtain more information about the image:
root@kvm:~# qemu-img info debian.img
image: debian.img
file format: raw
virtual size: 10G (10737418240 bytes)
