    Vulnerability  : files and device nodes ownership change to kvm group
    Problem type   : local

    Debian Bug     : 701649
    
    The recent security update for libvirt was found to cause a regression.
    The kvm/qemu processes weren't run as the `kvm` user anymore in order to
    fix the file/device ownership changes, but the processes where not
    correctly configured to use the `kvm` group either. When the user would
    try to run a virtual machine, the process was denied access to the
    /dev/kvm device node, preventing the virtual machine to run.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 0.8.3-5+squeeze5.
    
    We recommend that you upgrade your libvirt packages.
