Description of problem:
SELinux prevented pt_chown from using the terminal 3.
SELinux prevented pt_chown from using the terminal 3. In most cases daemons do not need to interact with the terminal, usually these avc messages can be ignored. All of the confined daemons should have dontaudit rules around using the terminal. Please file a bug report against this selinux-policy. If you would like to allow all daemons to interact with the terminal, you can turn on the allow_daemons_use_tty boolean.

How reproducible:
Everytime powering on a VM.

Steps to Reproduce:

Expected results:
VM should start.

Additional info:

Setting the recommended persistent sebool does NOT work!
-> 
[~]$ getsebool allow_daemons_use_tty
allow_daemons_use_tty --> on
