looking for a fast way to copy a template to a KVM guest

Question

My KVM guests each has a logical volume on the host to be the entire virtual disk. What will be a fast way to copy a template over to the guest's virtual disk? I tried to create a lzop compressed file first, then uncompress the file on the virtual disk. It costs 230 seconds to copy a 10GB template. But only 1GB of the 10GB template is occupied by a pre-installed OS. Any faster way to do this?

Partimag would probably work for what you're doing.
