Following our recent upgrade to ovirt-engine-4.5.0.7-0.9.el8ev and subsequent reboot of our self-hosted engine VM, we began noticing the following selinux denials in the logs:

SELinux is preventing /usr/bin/ovs-appctl from write access on the sock_file ovnsb_db.ctl.

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

If you believe that ovs-appctl should be allowed write access on the ovnsb_db.ctl sock_file 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:
# ausearch -c 'ovs-appctl' --raw | audit2allow -M my-ovsappctl
# semodule -X 300 -i my-ovsappctl.pp

No effect from restorecon:

[root@cs-hcim ~]# restorecon -rv /run/ovn/
[root@cs-hcim ~]# 

This suggests there is a bug in the selinux policy.
