    Bastian Blank discovered that libvirtd, a daemon for management of virtual
    machines, network and storage, would change ownership of devices files so they
    would be owned by user `libvirt-qemu` and group `kvm`, which is a general
    purpose group not specific to libvirt, allowing unintended write access to
    those devices and files for the kvm group members.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 0.8.3-5+squeeze4.
