Description of problem:
SELinux is preventing systemd from 'write' accesses on the sock_file virtlogd-sock.

*****  Plugin catchall (100. confidence) suggests   **************************

Si vous pensez que systemd devrait être autorisé à accéder write sur virtlogd-sock sock_file par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
Do
autoriser cet accès pour le moment en exécutant :
# ausearch -c "systemd" --raw | audit2allow -M my-systemd
# semodule -X 300 -i my-systemd.pp

Comment 1 Fedora End Of Life 2018-02-20 15:27:06 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle.
Changing version to '28'.

Comment 2 Lukas Vrabec 2018-02-27 13:46:30 UTC
Nicolas, 

Do you know when this happened? Are you able to reproduce it? 

THanks,
Lukas.

Comment 3 Nicolas Mailhot 2018-02-27 13:57:14 UTC
unfortunately, no, this system only serves as client to other stuff, so apart from updating it continuously to rawhide and accessing other things in firefox/evolution/ssh nothing much happens on it

I just reported the alerts that had accumulated over the past weeks

SELinux is preventing systemd from write access on the sock_file virtlogd-sock.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that systemd should be allowed write access on the virtlogd-sock sock_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'systemd' --raw | audit2allow -M my-systemd
# semodule -X 300 -i my-systemd.pp
