[libvirt-users] Unable to start guest

I have been picking away at this problem and I have not been able to resolve it yet and it appears quite puzzling to me, I am attempting to start a guest on KVM and receive 'error: An error occurred, but the cause is unknown'. I have a feeling this may be something simple I am overlooking. I have included log files and the xml of the guest at http://node4.smart-serv.net/~jeremy/libvirt/
