Ryan, Does this AVC also occur when you assign any of the other scheduling algorithms to a virtual server? I see this same issue, definitely not just limited to RR.

Seems like it's all.
This is a valid request. commit 5dc526e60870f336e388c7ee83ea8f955c87cbe8

When keepalived starts it will try to load the ip_vs* modules. It is able to load the ip_vs module, but fails to load the ip_vs_rr module. The AVC reads: type=AVC msg=audit(1433429290.228:446): avc: denied { module_request } for pid=2621 comm="keepalived" kmod="ip_vs_rr" scontext=system_u:system_r:keepalived_t:s0 tcontext=system_u:system_r:kernel_t:s0 tclass=system The keepalived service should be able to load any of the ip_vs* modules. Current workaround is to run the following command: /usr/sbin/setsebool -V -P domain_kernel_load_modules 1
