I need to mount some stuff with the loop device inside a domU, and see
that it doesn't have a loop device:

root@mars:[~]$ mount -o loop,noexec,nosuid,rw /.tmpfs /tmp
mount: Could not find any loop device. Maybe this kernel does not know
       about the loop device? (If so, recompile or `modprobe loop'.)

So, I try to modprobe the loop device, but can't.

root@mars:[~]$ modprobe loop
FATAL: Could not load /lib/modules/2.6.18-128.4.1.el5xen/modules.dep:
No such file or directory

root@mars:[~]$ uname -a
Linux mars.softdux.com 2.6.18-128.4.1.el5xen #1 SMP Tue Aug 4 20:51:12
EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

It seems like I need the kernel-headers, but when I try and install
them, I see that I have the wrong kernel loaded, and take it that this
comes directly from the XEN dom0.

So, the question is, how would I be able to get the kernel-dev header
for 2.6.18-128.4.1.el5xen installed inside the domU?
