When interviewed in October 2008, Red Hat global chief executive Jim Whitehurst said virtualization was one of the company's key priorities. "Virtualization should be part of the operating system, not a separate layer," he said at the time.
Virtualization in RHEL 5.3 has been improved, including the ability to make larger virtualized machines — supporting up to 32 virtual CPUs and 80GB of RAM — in x86-64 environments. RHEL is currently used to run a number of large virtualization instances, including Amazon's elastic computing cloud, known as EC2.
RHEL 5.3 also includes support for Intel's latest chip architecture, Core i7, code-named Nehalem. Released in August last year, Core i7 is the successor to Intel's Core 2 Duo architecture.
Finally, RHEL 5.3 includes the Open Java Development Kit, an open-source implementation of Java SE 6 supported by Sun. This inclusion is intended to support Red Hat's Java application server, JBoss.
