Description of problem:
After OVN fresh install I saw AVC's errors:

[root@localhost ~]# ls -lZ /var/log/lastlog
-rw-r--r--. root root system_u:object_r:lastlog_t:s0   /var/log/lastlog

Whatever's (re)creating it should be calling restorecon.

Were it the correct label, this would work: 

   allow sshd_t lastlog_t : file { ioctl read write create getattr setattr lock append open } ;
