Description of problem:
When I set 'Optimize for virt' changes are made to my volume for Virtual Image hosting.  But days, or weeks later, I can't easily see anything indicating that one volume is optimized for virt while another isn't

Version-Release number of selected component (if applicable): 2.1


How reproducible: 100%


Steps to Reproduce:
1. Press optimize for virt
2. look at screen
3. see anything indicating that a volume is optimized for virt?

Actual results:
no visual difference between volumes

Expected results:
some kind of hint that there are different settings on this volume
