Description of problem:
I was trying to start a VM which previously started without issues after upgrading qemu to latest virt-preview.
SELinux is preventing virtlogd from 'write' accesses on the fifo_file /run/systemd/inhibit/36.ref.

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

If si crede che virtlogd dovrebbe avere possibilità di accesso write sui 36.ref fifo_file in modo predefinito.
Then si dovrebbe riportare il problema come bug.
E' possibile generare un modulo di politica locale per consentire questo accesso.
Do
allow this access for now by executing:
# ausearch -c 'virtlogd' --raw | audit2allow -M my-virtlogd
# semodule -X 300 -i my-virtlogd.pp
