Ok, I created a domU with the following command, and I see the image I 
created, but I can't find the resulting config file. Where'd it go? Nothing 
in /etc/xen or /etc/libvirt has a recent timestamp. I can start the image 
with virsh and connect to its console, but I don't know where it stores its 
configuration. I don't see any files in /etc/sysconfig that contain the 
name of my domU (asskicker1). (I grepped all of /etc for that string.) From 
all the documentation I'm finding I'm supposed to put a config file in 
/etc/xen/auto to make the domU load at boot time but I can't fine the 
config file to make that happen. Looking at the initscript for 
libvirt-guests, it seems I'm supposed to list boot-time guests in a new 
file called /var/lib/libvirt/libvirt-guests.
