The 'D' is now capital to clarify pronunciation. DBus service name is kept as '/Tuned' not to break backward compatibility. This will also need update of downstream tests which rely on the specific output strings containing the name. Signed-off-by: Jaroslav Škarvada <jskarvad@redhat.com>

|
|
|
|
This procedure activates a selected *TuneD* profile on your system.
|

|
* The `tuned` service is running. See xref:installing-and-enabling-tuned_{context}[] for details.
|

----
|
|
# 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
|
