Xen users - Mar 2009 - What storage system to use for xen? img or phy lvm

I was wondering if img''s are a lot slower then using  lvm on dom0
partition?
The domU will be handling web site and mail servers.

I used to run img files at first.  For several reasons, I switched to
using LVM on Dom0.  The first was the ease of resizing partitions later as
needed.  Another was the option to do snapshot backups from the logical
volumes.

Although I haven''t done any quantitative testing, it feels as though it
is
quicker using LVM.

I am using paravirtualized Linux DomU''s on a Debian based Dom0 OS. 
Similar to your setup, my machines primarily operate as mail servers, web
server, DNS, and ftp server.
