SELinux is preventing /usr/bin/pulseaudio from using the 'setsched' accesses on a process.

starting new virtual domain ... it might be possible, I am doing something wrong, this was quite hackish change in the configuration of the guest.

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

If you believe that pulseaudio should be allowed setsched access on processes labeled svirt_t 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 pulseaudio /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
