compute log

Description of problem:

I am working with gluster storage configured as my cinder and glance backend. 

when I try to create a snapshot to an instance, the snapshot moves from Queuing to Deleting. 

compute log shows that there is an invalid option in qemu-img command 

Version-Release number of selected component (if applicable):

openstack-nova-compute-2013.2-0.24.rc1.el6ost.noarch

How reproducible:

100%

Steps to Reproduce:
1. install gluster as cinder and glance backend 
2. create an image and boot an instance from the image 
3. create a snapshot from the instance 

Actual results:

we fail to create a snapshot 

Expected results:

we should be able to create the snapshot
