Description of problem:
Having OpenVSwitch started on an upgraded fedora 27 system
SELinux is preventing modprobe from 'module_load' accesses on the system Unknown.

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

If you believe that modprobe should be allowed module_load access on the Unknown system 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 'modprobe' --raw | audit2allow -M my-modprobe
# semodule -X 300 -i my-modprobe.pp
