Comment 4 for bug 1782206

Ok, now we finally know it is about qemu&kernel patches - I'll add tasks for that.
Still haven't seen any xen references, setting that to incomplete.

But given how new it is I'd punt this from 19.04 to 19.10 where things in kernel&qemu will have matured and be safer to use.

If you are not ok with this please outline important use cases that will be inhibited.
All changes are "just" adding definitions, no actual code added - but I'm somewhat afraid of hidden dependencies - especially since we have no associated testcase and it would need special (very new) hardware t be tested.
