Description

This test case tests the basic functionality of tuned tool. This tool can statically and dynamically tune your system according to selected profile.

Setup

Start tuned (via systemd):
```
# systemctl start tuned.service
```
List all available profiles:
```
# tuned-adm list
```
Let tuned to recommend you the best profile for your system:
```
# tuned-adm recommend
```
```
# tuned-adm list
```
Try to switch between profiles, e.g. for powersave profile:
```
# tuned-adm profile powersave
```
Check if the profile was really set by:
```
# tuned-adm active
```
Try several other profiles, you can use the:
```
# pmtd-selinux-test
```
to automatically go through all available (installed) profiles in a loop and output SELinux AVCs.
Try to generate tuned profile from powertop's suggestions:
```
# powertop2tuned test-profile
```
In this generated profile all powertop's tunings are initially disabled, you can selectively enable them by editing /etc/tuned/test-profile/script.sh.
Try to switch to generated profile:
```
# tuned-adm profile test-profile
```
Switch back to balanced profile:
```
# tuned-adm profile balanced
```
Remove generated profile:
```
# rm -rf /etc/tuned/test-profile
```
When done switch tuned completely off by:
```
# systemctl stop tuned.service
```
Check if the tuned process is not left running by:
```
# pgrep -l tuned
```

No errors while switching / generating profiles.
No SELinux AVCs.
Tuned should recommend the 'balanced' profile in the most cases on the bare metal, the 'virtual-guest' profile when running in the virtual machine. The rules for selecting the best profile can be customized in the /etc/tuned/recommend.conf (you can use /usr/lib/tuned/recommend.conf as a template, copy it to the /etc/tuned and edit).
No left tuned process when switched off (ksmtuned not counted).
