I updated my system this morning. Updated packages included a new
kernel and some SElinux stuff among other things (the complete list is
attached). I now find that neither of my QEMU/KVM guests (one Fedora,
one Windows 10) have Internet access, though they do have access to my
host. They were both working perfectly before the update. Nothing else
in my system has changed (in particular, I haven't touched the Firewall
rules and the last updates to NetworkManager or Qemu were several days
ago).
I rebooted to the previous kernel - no difference.
I set SElinux to permissive and rebooted the Fedora guest - no
difference.
Before trying to downgrade the entire update, is there anything else I
can do?
