Looks like RHEL/Centos5 kernel? If so, the loop module is already
compiled as a module. You just need to put it at the right place.
Here's from mine:

# uname -a
Linux eoffice03 2.6.18-128.1.10.el5xen #1 SMP Wed Apr 29 14:24:51 EDT
2009 x86_64 x86_64 x86_64 GNU/Linux
# modinfo loop
filename:       /lib/modules/2.6.18-128.1.10.el5xen/kernel/drivers/block/loop.ko
alias:          block-major-7-*
license:        GPL
srcversion:     82DB6DB3DABF3B945D6394D
vermagic:       2.6.18-128.1.10.el5xen SMP mod_unload gcc-4.1
parm:           max_loop:Maximum number of loop devices (1-256) (int)

My guess is your domU was created manually, and whoever created it
forgot to copy  /lib/modules/2.6.18-128.4.1.el5xen directory.
