Dear Red Hat Customers and Partners:
Today, we are pleased to announce the availability of the Beta release
of Red Hat Enterprise Linux 5.8. Red Hat’s proven, long lifecycle model
considers customer needs and preferences while enabling a stable and
feature-rich operating system environment. Through minor releases, such
as the Red Hat Enterprise Linux 5.8, Red Hat Enterprise Linux customers
experience significant and ongoing value from their subscriptions.
This beta release includes a broad set of updates to the existing
features and also provides new functionality, particularly in the areas
of power and security management, and virtualization. Support for a
range of new hardware is also included.
Key functionality in this beta is as follows:
Installation and Operation Management
-------------------------------------
* Support for Power Management Quality of Service (QoS) provides
automatic power management 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
in lieu of achieving power savings.
* The configuration of IP over Infiniband (IPoIB) adapters is now
supported by the system installer, making installation of Infiniband
adapters easier.
* 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 and storage driver enhancements increase the number of devices
supported.
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.
Virtualization
--------------
* 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 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 Linux 5 KVM hosts.
* Additional KVM improvements increase the usability and stability of
KVM hosts and Red Hat Enterprise Linux guests.
* Xen enhancements provide improved guest performance, improved logging
for debug, and virtual disk re-sizing while a guest is running.
