Totally.   If you want to name the virtual system "foosball" you can, or 
you can just decide to provision based on profiles.   If you do that, 
the best invocation is:

koan --virt --profile=profile-xen --server=cobblerBox --virt-name=foosball

That way you get a better name than the one cobbler will generate for 
you, and it will make more sense when you look at it in virsh or 
virt-manager later.

The reason to use virt provisioning based on the system would be if you 
wanted DHCP control, or if you were doing per-system templating.   In 
most cases, I just use --profile for virt.
