RHBA-2012:0924 - tuned bug fix and enhancement update

Synopsis

tuned bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated tuned packages that fix two bugs and add two enhancements are now available for Red Hat Enterprise Linux 6.

Description

The tuned package contains a daemon that tunes system settings dynamically. It does so by monitoring the usage of several system components periodically.

This update fixes the following bugs:

  • When the diskdevstat or netdevstat tool was run with wrong command-line arguments, the tool returned a compilation error and exited. Both tools have been fixed to check the command-line arguments. With this update, a short usage help message is printed in the described scenario, describing the available options. (BZ#747210)

  • When the tuned utility was running in a virtual guest, the disk-scheduler setting was not applied on virtual disks (vd*). Now, default configuration files that cover virtual disks have been updated and the disk-scheduler setting is now applied on the virtual disks in virtual guests. (BZ#725497)

This update adds the following enhancements:

  • With this update, a new "virtual-host" profile has been added to the tuned package, providing fine-tuned profile for hypervisors managed by Red Hat Enterprise Virtualization Manager. (BZ#740976)

  • With this update, a new "virtual-guest" profile for virtual systems has been added to the tuned package, providing fine-tuned profile for Red Hat Enterprise Linux 6 KVM virtual guests. (BZ#740977)

Users of tuned are advised to upgrade to these updated packages which fix these bugs and add these enhancements.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
