Description of problem:
juste lauching gnome boxes
SELinux is preventing /usr/bin/qemu-system-i386 from 'create' accesses on the netlink_route_socket .

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

If you believe that qemu-system-i386 should be allowed create access on the  netlink_route_socket 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 qemu-system-i38 /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
