Red Hat Enterprise Linux 5.8 Announcement

We’re pleased to announce the general availability of the Red Hat Enterprise Linux 5.8 operating system with new and improved functionality for enhanced performance, flexibility, and security. Our commitment to continuous innovation enables Red Hat Enterprise Linux to remain a scalable and trusted data center platform accommodating mission-critical enterprise workloads in physical, virtual, and cloud IT environments. And, the extension of the Red Hat Enterprise Linux 5 and 6 life cycle to 10 years means that our customers can plan IT deployments and migrations according to their business needs, not ours. Red Hat Enterprise Linux 5.8 supports new hardware platforms and includes the following enhancements:

Hardware Support and Streamlined Installation

* Support for Power Management Quality of Service (QoS) provides automatic power management policy at the device level for managing latency and throughput based on QoS needs. During critical production windows, system administrators can enforce a high-performance, low-latency mode. * New iotop support enables the monitoring of I/O resources, such as storage devices, at the process level, providing insight into potential performance issues. * PCI-e 3.0 enablement provides support for new and emerging PCI-e 3.0 adapters. * Network, storage, and graphic driver enhancements are provided for new hardware support. * The configuration of IP over Infiniband (IPoIB) adapters is now supported by the system installer, making installation of Infiniband adapters easier.


* KVM scalability enhancements have increased the maximum supported virtual guest size from 128 to 256 virtual CPUs, extending the reach of virtualization deployments to large-scale workloads. * The spice-client package now adds support for Red Hat Enterprise Virtualization 3.0 and Red Hat Enterprise Linux 6.2 hosts. These improvements also allow users to access their desktop virtual machines over a WAN connection in addition to the local network. * KVM enhancements include improved guest boot times and improved clock and timer support. The KVM hypervisor has updated real time clock (RTC) support to improve the performance of Red Hat Enterprise Linux 6 guests on Red Hat Enterprise Virtualization or Red Hat Enterprise Linux 5 KVM hosts. * Additional KVM improvements increase the manageability and stability of KVM hosts and Red Hat Enterprise Linux guests. Many of these enhancements are in support of Red Hat Enterprise Virtualization 3.0. * Xen enhancements provide improved guest performance, improved logging for debug, and virtual disk re-sizing while a guest is running.

Security Management

* OpenSCAP (Open Security Content Automation Protocol) support is now compliant with the SCAP 1.1 (Security Content Automation Protocol) specification, the most recent standard framework defined by National Institute of Standards and Technology (NIST) for creating a standardized approach for maintaining secure systems. * Red Hat Enterprise Linux 5 has been tested to the United States Government Configuration Board (USGCB) baseline and now meets the USGCB recommendations for government agencies following USGCB guidance for secure configuration policies.

Subscription Asset Manager (SAM) Beta Availability

We continue to invest in applications and functionality that provide our customers more flexibility and control over their Red Hat Enterprise Linux deployments. Accordingly, we are pleased to announce the Beta availability of the Red Hat Subscription Asset Manager (SAM). SAM is an asset tracking and inventory management application designed for on-premise deployment. SAM is the newest component in the Red Hat Entitlement offerings and will be included as part of your Red Hat Enterprise Linux subscription.
