Ovirt itself doesn't control the storage.<br>
<br>
Under the storage tab click on the storage domain you're having issues with and check to see if the images themselves have been deleted or if they are still there. When you delete a virtual machine you have the option to delete the virtual image as well.<br>
<br>
If a virtual machine has more than one image then I'm not sure how this is handled as I've only used single images for virtual machines. Any additional storage I need I handle over NFS directly to the virtual machine.<br>
<br>
Perhaps ovirt doesn't automatically delete secondary images? Either way you should be able to delete them manually and reclaim space.<br>
