Comment 2 for bug 1696471

Hi Martin,
I'm currently trying to clean up bugs that were missed or got no update.
First I have to beg your pardon for missing it in the first place.

I have run spice sessions without that showing up, so I checked what that actually is about.
In general that directory is to plug configs for the gssapi - see some libvirt ref at [1].

This is enabled since ages, but I haven't heard of any issues. Which either means it works fine or no one is actually using it.
I'd assume your setup has a SASL/GSSAPI configured more than vnc/spice to trigger this.
If you'd have any details on this part of your setup for better reproducibility of the issue, that would be great.
In general sharing a guest xml could help so I can kind of bisect through it if/how to trigger it.

Alternatively it seems only be used when you use the non TLS socket.
Your bug report states only default networks as modified, but maybe this differs from the env this pops up. Could you could check if you have any changes made to either
/etc/sasl2/libvirt.conf or to listen_tls in /etc/libvirt/libvirtd.conf.
