We create the /etc/modprobe.d/kvm.rt.tuned.conf file at
every boot. However, there's nothing that guarantees that
the kvm module will be loaded after tuned. Indeed, it's
possible to reproduce a race where the kvm module is loaded
before tuned. When this happens, the kvm module will be
loaded with incorrect parameters as the kvm.rt.tuned.conf
file doesn't exist.
The solution to this problem is to create the kvm.rt.tuned.conf
file only if it doesn't exist and delete it when changing
profiles.
