LV cloning?

I am using Virtualbox for setting up a bunch of windoze xp vms. I am setting up a gold vm as a template and want to script the cloning of the images (lv). I was hoping that I could do that on the iSCSI side to just clone the logical volumes and script that to happen weekly.
Any ideas or do I have to do that on the client side?
Thanks

Nothing can be done on our side other then the Volume Replication feature, the rest would be on the host side. Other then that I do not have any information to assist you.
