Comment 58 for bug 1787405

Arr, thanks chrome :-/
Such a nice update lost, well let me rewrite it in a shorter fashion:

1. the patches seem good, thanks for the effort to help backporting
2. the extra changes seem safe to me
3. I added a patch on top to get it working with virt-aa-helper
   That is essentially an extension to [1], while hotplug is already covered by [2] (always
   easier as at this time of the livecycle it can inspect the attributes).
4. Now please try the PPA at [3]

If confirmed working I think the next steps are:
- bring the virt-aa-helper change upstream
- some more testing and regression check
- get all of this into current Ubuntu development release
- plan SRU releases to 18.10/18.04 then
