WARNING regarding 4.3.x kernel

[Chris Murphy]

Weird. I've been using virt-manager with kernel 4.3.3 and 4.4.0 on
Fedora 23 for some time without problems. Maybe check AVC messages?

ausearch -m AVC

Maybe it's worth relabeling:

restorecon -rv /

I don't know why but even after a clean install and no updates,
restorecon fixes labels. It's like they aren't set correctly to start
with for some reason. And then after any update I run it and it fixes
more things each time. Kinda annoying really. I don't feel like I
ought to need to relabel manually after every update. Maybe more than
one label is valid, just that one is more valid than another and
that's why the install label is sometimes different from post-install
label.
