SELinux is preventing /usr/lib/virtualbox/VBoxManage from write access on the fifo_file fifo_file.

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

If you believe that VBoxManage should be allowed write access on the fifo_file 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:
# grep VBoxManage /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
