This is to announce tuned-2.4.0, a stable release. Tuned is a tool that performs monitoring and adaptive configuration of the system according to selected profile. The 2.4.0 contains many bug fixes and also introduces new features. Noteworthy changes since previous release: - fixed traceback if profile cannot be loaded (rhbz#953128) - powertop2tuned: fixed traceback if rewriting file instead of directory (rhbz#963441) - daemon: fixed race condition in start/stop - improved timings, it can be fine tuned in /etc/tuned/tuned-main.conf (rhbz#1028122) - throughput-performance: altered dirty ratios for better performance (rhbz#1043533) - latency-performance: leaving THP on its default (rhbz#1064510) - used throughput-performance profile on server by default (rhbz#1063481) - network-latency: added new profile (rhbz#1052418) - network-throughput: added new profile (rhbz#1052421) - recommend.conf: fixed config file (rhbz#1069123) - spec: added kernel-tools requirement (rhbz#1073008) - systemd: added cpupower.service conflict (rhbz#1073392) - balanced: used medium_power ALPM policy - added support for >, < assignment modifiers in tuned.conf - handled root block devices - balanced: used conservative CPU governor (rhbz#1124125) - plugins: added selinux plugin - plugin_net: added nf_conntrack_hashsize parameter - profiles: added atomic-host profile (rhbz#1091977) - profiles: added atomic-guest profile (rhbz#1091979) - moved profile autodetection from post install script to tuned daemon (rhbz#1144067) - profiles: included sap-hana and sap-hana-vmware profiles - man: structured profiles manual pages according to sub-packages - added missing hdparm dependency (rhbz#1144858) - improved error handling of switch_profile (rhbz#1068699) - tuned-adm: active: detect whether tuned deamon is running (rhbz#1068699) - spec: removed active_profile from RPM verification (rhbz#1104126) - plugin_disk: readahead value can be now specified in sectors (rhbz#1127127) - plugins: added bootloader plugin (rhbz#1044111) - plugin_disk: added error counter to hdparm calls - plugins: added scheduler plugin (rhbz#1100826) - added tuned-gui with profile editor Download: http://fedorahosted.org/releases/t/u/tuned/tuned-2.4.0.tar.bz2 Upstream homepage: http://fedorahosted.org/tuned/

[tuned] #49: Provide a way to disable dynamic updates per plugin

#49: Provide a way to disable dynamic updates per plugin --------------------------+--------------------- Reporter: ework | Owner: Type: enhancement | Status: new Priority: major | Component: plugins Version: 2.0 | Keywords: net Blocked By: | Blocking: --------------------------+--------------------- I use synergy to share a mouse & keyboard between my desktop and laptop. Whenever I start to download something (for example a Fedora ISO), I lose my connection for about 30 sec due to the ethernet interface speed change. Even worse the download fails because the connection is lost for this brief period of time. I'd suggest that at least this change doesn't occur when on AC as a default policy, but for me personally a way to disable dynamic updates per plugin without having to hack the python code would be nice. I couldn't seem to find anywhere in the documentation that mentions how to do this. -- Ticket URL: <https://fedorahosted.org/tuned/ticket/49> tuned <https://fedorahosted.org/tuned/> A daemon that performs monitoring and adaptive configuration of devices in the system.

NO_HZ FULL will not work in realtime-virtual-guest
by Yang, Tao Y 28 Jul '15

28 Jul '15

Hi ALL, I am running the RHEL 7.1 in both host and guest for a low latency network performance test. I use the realtime-virtual-host for the host and realtime-virtual-guest for guest. These optimize really improve my network performance in the RFC 2544 throughput test. But I fund there are error in the guest OS, when I enable the nohz_full. Looks like the nohz_full can't be enable in the guest OS. Do we need remove the nohz_full in the realtime-virtual-guest for guest? Here is information from the Guest OS.
