Description of problem:
I'm in the process of configuring Openstack (keystone service atm.), and noticed this alert
SELinux is preventing /usr/bin/python2.7 from using the 'setsched' accesses on a process.

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

If you believe that python2.7 should be allowed setsched access on processes labeled keystone_t 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 keystone-all /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
