Cause:
cinder-volume node should install qemu-img before volume creation. Using follow:
apt-get install qemu

I think this is up to your install or distribution that you're using. In other words, Cinder does not install packages, that's deployment. What you're reporting here is not a bug, if there's no info in the docs about installing qemu tools that is possibly something we could add.

What OpenStack distribution are you using?

[Yang Luo (hsluoyz)]

@John

I'm using 1:2014.1.3-0ubuntu1~cloud0 distribution. Followed official icehouse docs, this guide didn't give a shot about qemu install thing:
http://docs.openstack.org/icehouse/install-guide/install/apt/content/

[John Griffith (john-griffith)]

@Yang Lou

Thanks a lot for the quick follow up, unfortunately I just took a look at the current docs and it's missing there as well. Let's get something logged against docs and see if we can get something submitted to clear this up.

Thanks a lot for bringing this up and logging the issue.
