It seems libvirt have no acess to the file . need make some configurations for libvirt to work with openstack
Hope the following steps for Redhat 6.3/6.4 can help you :

  1.# chown root:root /var/run/libvirt/qemu /var/lib/libvirt/qemu /var/cache/libvirt/qemu

  2.Edit /etc/libvirt/qemu.conf
    # The user ID for QEMU processes run by the system instance.
    user = "root"
    # The group ID for QEMU processes run by the system instance.
    group = "root"

  3.Restart libvirt service
    #service libvirtd restart

Can you help with this problem?
