Description rockonthemoonfm 2011-03-19 15:54:55 UTC
SELinux is preventing /usr/bin/python from 'write' accesses on the file cpufv.

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

If you believe that python should be allowed write access on the cpufv file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep tuned /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
