Updated tuned packages that fix two bugs and add two enhancements are now available for Red Hat Enterprise Linux 6.
The tuned package contains a daemon that tunes system settings dynamically. It does so by monitoring the usage of several system components periodically.
- 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.
- 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.
- 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.
- 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.
Users of tuned are advised to upgrade to these updated packages which fix these bugs and add these enhancements.
