RHEL6.4 KVM Virtualization storage pool recomendation

Hi, I was wondering if it's better to create VMs as image files or as LVM volumes. Is there any kind of document with recommendations about this?

Our VMs are using ~200G image files and we want know if there's any improvement at all moving those to LVM.

Thanks in advance.

What is the backing storage?

If it's SAN or iSCSI, then using lvm will be ideal since using that bypasses using filesystem layer on host.

If it's NFS, then files will be the only option.

I believe LVM is better since it bypasses creating a filesystem using lun and using file based storage on it.
