Description of problem:
Open the "Details" panel in Control Center
SELinux is preventing /usr/lib/systemd/systemd-hostnamed from 'open' accesses on the file /sys/devices/virtual/dmi/id/chassis_type.

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

If you believe that systemd-hostnamed should be allowed open access on the chassis_type 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:
# grep systemd-hostnam /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
