.Procedure
|
|
|
|
. Optionally, you can let *TuneD* recommend the most suitable profile for your system:
|
|
+
|
|
[subs="quotes"]
|
|
----
|
|
# tuned-adm recommend
|
|
|
|
[replaceable]_balanced_
|
|
----
|
|
|
|
. Activate a profile:
|
|
+
|
|
[subs="quotes"]
|
|
----
|
|
# tuned-adm profile [replaceable]_selected-profile_
|
|
----
|
|
+
|
|
Alternatively, you can activate a combination of multiple profiles:
|
|
+
|
|
[subs="quotes"]
|
|
----
|
|
# tuned-adm profile [replaceable]_profile1_ [replaceable]_profile2_
|
|
----
|
|
+
|
|
.A virtual machine optimized for low power consumption
|
|
====
|
|
The following example optimizes the system to run in a virtual machine with the best performance and concurrently tunes it for low power consumption, while the low power consumption is the priority:
|
|
|
|
----
|
|
# tuned-adm profile virtual-guest powersave
|
|
----
|
|
====
|
|
|
|
. View the current active *TuneD* profile on your system:
|
|
+
|
|
[subs="quotes"]
|
|
----
|
|
# tuned-adm active
|
|
|
|
Current active profile: [replaceable]_selected-profile_
|
|
----
|
|
|
|
. Reboot the system:
|
|
+
|
|
----
|
|
# reboot
|
|
----
|
|
|
|
.Verification steps
|
|
|
|
* Verify that the *TuneD* profile is active and applied:
|
|
+
|
|
----
|
|
$ tuned-adm verify
|
|
|
|
Verification succeeded, current system settings match the preset profile.
|
