Red Hat Enterprise Linux 5.4 released

Enhancements in virtualization, developer tools and hardware support

Red Hat has released Version 5.4 of its Red Hat Enterprise Linux operating system. This new version comes with more options for virtualization, more developer tools and new modifications to speed hardware performance, according to the company.

Among the new virtualization features include support for kernel-based virtual machine technology, which allows servers to run unmodified Linux or Windows images, each with their own network card, disk and other components. It also includes support for Intel Virtualization Technology for Directed I/O, which allows multiple virtual machines running on Intel Xeon Processor 5500 Series-based processors to directly share input/output devices.

RHEL 5.4 has also been modified to take advantage of the full featuresets of the Intel Xeon 5500 and AMD Istanbul lines of processors. To aid in networking, RHEL 5.4 runs the Generic Receive Offload-based software and now supports Fibre Channel over Ethernet. The new version of the OS also includes the Systemtap performance monitoring toolset, which can be used to profile and monitor C++ applications.

RHEL can be used in data centers to run servers.
