Description of problem:
SELinux is preventing systemd-machine from 'read' accesses on the file Unknown.

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

If you believe that systemd-machine should be allowed read access on the Unknown 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-machine' --raw | audit2allow -M my-systemdmachine
# semodule -X 300 -i my-systemdmachine.pp
