Description of problem:
I have install openvswithtch and started the service via systemctl
SELinux is preventing /usr/bin/uuidgen from 'getattr' accesses on the chr_file /dev/random.

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

If you believe that uuidgen should be allowed getattr access on the random chr_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:
# grep uuidgen /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
