I'm 99% sure it has something to do with the firewall. Thing is, I
haven't touched the firewall rules. Nevertheless I see this:

I tried reloading firewalld and got the same result. I fired up the
firewall applet and suddenly the guests had network access, even though
I didn't change anything. I quit the applet and boom, the guests lost
network access again. Fired it up once more, but this time the guest
access didn't come back.
I don't know if any of this is repeatable. Time to slaughter a chicken
by the light of the moon?
