+Prasanna

Prasanna changed qemu code to reuse the glfs object for adding multiple disks from same volume using refcounting. So the memory usage went down from 2GB to 200MB in the case he targetted. Wondering if the same can be done for this case too.

Prasanna could you let us know if we can use refcounting even in this case.
