[Pkg-libvirt-maintainers] Bug#764894: virt-manager: USB devices are generally redirected to VMs

After some thinking I'd guess that there are actually two bugs:

1) That virt-manager automatically redirects without asking (because
apparently it now has a menu (Virtual Machine/Redirect USB Device) which
should do just that.
Actually IMHO it should generally happen only manually, because it's
quite annoying if everytime I put in some USB device, all my
virt-manager consoles would ask for it.

2) A security hole in the polkit configuration, in that it allows any
user actually redirect - and via that - gain full access to such USB
device.


So only if root has manually (via configuration) allowed a user to
redirect all or specific USB devices polkit should even grant the whole
thing.
But even then, it shouldn't happen automatically, but only when the user
really says "oh, yeah,... go and redirect".


Cheers,
Chris.
