Description Vít Ondruch 2011-04-01 11:27:56 UTC
SELinux is preventing /usr/bin/python from 'setattr' accesses on the directory /sys.

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

If you believe that python should be allowed setattr access on the sys directory 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 yum /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
