Expected results:
No segs

Additional info:

Note they all seem to be ..071c8 addresses, so it seems to be the same address, which also I think is the IP which seems pretty weird/worrying.
I don't think I was doing anything odd at the time.
I have one extra added polkit rule:
[root@major dg]# cat /etc/polkit-1/rules.d/10.virt.rules 
polkit.addRule(function(action, subject) {
        polkit.log("action=" + action);
        polkit.log("subject=" + subject);
        var now = new Date();
        polkit.log("now=" + now)
        if ((action.id == "org.libvirt.unix.manage" || action.id == "org.libvirt.unix.monitor") && subject.isInGroup("virt")) {
        return polkit.Result.YES;
        }
        return null;
        });

but I've not been doing anything with virt on this machine today, probably was on previous days.

Journalctl doesn't say much more:
