= Merged TuneD profiles

[role="_abstract"]
As an experimental feature, it is possible to select more profiles at once. *TuneD* will try to merge them during the load.

If there are conflicts, the settings from the last specified profile takes precedence.

.Low power consumption in a virtual guest
====
The following example optimizes the system to run in a virtual machine for 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
----
====

WARNING: Merging is done automatically without checking whether the resulting combination of parameters makes sense. Consequently, the feature might tune some parameters the opposite way, which might be counterproductive: for example, setting the disk for high throughput by using the `throughput-performance` profile and concurrently setting the disk spindown to the low value by the `spindown-disk` profile.
