Title:
  Nova-Compute-kvm fails in ubuntu server 13.04

Status in OpenStack Compute (Nova):
  Invalid
Status in nova package in Ubuntu:
  Won't Fix

Bug description:
  So I have installed the latest ubuntu server 13.04 where KVM package has been replaced by qemu-system-x86.
  When i install nova-compute-kvm, it doesn't start because there is no connection to libvirt ! I have tried to used nova-compute-qemu instead of nova-compute-kvm but the problem still persists (see Log below) 

  My processor supports virtualisation and i used to create VMs normally
  when i had Folsom. After updating ubuntu server 12.10 to ubuntu 13.04,
  it seems that things changed and communication to libvirt is lost.
  This is the nova-compute.log :
