USB devices become available with very dangerous chown -R of /dev/devices/...usb

Dangerous edits, as per other filed bugs, to /etc/apparmor.d/abstractions/libvirt-qemu do not work.

In Virtual machine manager, and in virsh, security "model" is not enabled / available / listed. No security is listed in the domain XML file.

Changing /etc/apparamor/abstractions/libvirtd does not work.

Rebooting dozens of times does not work.

This is in many ways the opposite of bug #588369.

I am filing as a bug because all the utilities and their docs mention apparmor, but fail completely and _silently_ when this problem occurs, and there is not even howto assistance. For example, the virtual manager GUI leaves the security model under "overview" as unselectable, and leaves the user completely in the dark.

qemu.conf has the line:
  # security_driver = "selinux"

The only file in /etc/apparmor.d/libvirt is the TEMPLATE file. No UUID-suffixed files exist.

Done! But I don't think it did anything.

A message was issued in the terminal:
    Package libvirt not installed and no hook available, ignoring
That may be because the "package" is "libvirt", but the "package" is "libvirt-bin".

What "various pieces of information" should I gather, if the automated tool cannot do it?
