Description of problem:
I started a VM in virt-manager.
SELinux is preventing virtlogd from 'write' accesses on the fifo_file /run/systemd/inhibit/36.ref.

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

If you believe that virtlogd should be allowed write access on the 36.ref fifo_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 'virtlogd' --raw | audit2allow -M my-virtlogd
# semodule -X 300 -i my-virtlogd.pp
