Description of problem:
Can not boot URL install in virt-manager. 

Version-Release number of selected component (if applicable):

qemu-kvm-0.12.3-6.fc13.x86_64
kernel-2.6.33.1-19.fc13.x86_64

How reproducible:
Be every time I try

Steps to Reproduce:
1. Following the direction of creating new VM in virt-manager
2. Finish all the things and 
  
Actual results:
virt-manager can not boot. The hypervisor is xenner. I can not make sure that xenner or libvirt cause the problem. Here is the error log in virt-manager.

PS: The same error also appears on libvirt-0.7.7-1.fc13.x86_64. If I choose KVM hypervisor on libvirt-0.7.7-1.fc13.x86_64, KVM will not boot but it shows another errors. Now the error on KVM hypervisor is fixed in libvirt-0.7.7-2.fc13.x86_64, nevertheless, xenner's continues. 

Expected results:
