TuneD project: https://tuned-project.org/

TuneD is a system tuning service for Linux. It provides a number of pre-configured tuning profiles, each optimized for unique workload characteristics, including CPU-intensive job needs, storage/network throughput responsiveness, or power consumption reduction.

Install TuneD on OpenSUSE:

sudo zypper install tuned

Enable and start the TuneD service.

sudo systemctl enable --now tuned
Created symlink /etc/systemd/system/multi-user.target.wants/tuned.service → /usr/lib/systemd/system/tuned.service.

You can now view the standard profile:

sudo tuned-adm active
Current active profile: balanced

List all TuneD profiles that are available on your system:

sudo tuned-adm list
Available profiles:
- balanced - General non-specialized tuned profile
- cpu-partitioning - Optimize for CPU partitioning
- desktop - Optimize for the desktop use-case
- latency-performance - Optimize for deterministic performance at the cost of increased power consumption
- mssql - Optimize for MS SQL Server
- network-latency - Optimize for deterministic performance at the cost of increased power consumption, focused on low latency network performance
- network-throughput - Optimize for streaming network throughput, generally only necessary on older CPUs or 40G+ networks
- powersave - Optimize for low power consumption
- throughput-performance - Broadly applicable tuning that provides excellent performance across a variety of common server workloads
- virtual-guest - Optimize for running inside a virtual guest
- virtual-host - Optimize for running KVM guests
Current active profile: balanced

We can set the profile to virtual-host. This optimizes the host for running KVM guests.

sudo tuned-adm profile virtual-host

Check that the TuneD profile has been updated and that virtual-host is now active.

sudo tuned-adm activeCurrent active profile: virtual-host

Make sure there are no errors.

sudo tuned-adm verify
Verfication succeeded, current system settings match the preset profile.
See TuneD log file ('/var/log/tuned/tuned.log') for details.

Verify the log file for possible errors.
