Hi Steven (Great name!),

The config files should be (by default) in /etc/xen/ - however there is 
no requirement for them to be there. It will be the file that determines 
the configuration of the DomU - ie where the storage lives, etc etc.

For example, my template one that lives as /etc/xen/template.vm contains:
name = "template.vm"
memory = 1024
vcpus = 2
disk = [ 'phy:/dev/RAID5/template.vm,xvda,w' ]
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'
vif = [ "mac=00:16:36:35:35:97,bridge=br0,script=vif-bridge" ]
kernel="/usr/lib/xen/boot/pv-grub-x86_64.gz"
extra="(hd0)/boot/grub/grub.conf"
