Red Hat Enterprise Linux 4.5 Beta Released As V5 Prepped For Launch
With Enterprise Linux 5 set to ship in March, Red Hat has put into beta testing an update for Enterprise Linux 4 that makes it virtualization-friendly.
Red Hat Enterprise Linux 4 Update 5, which moved into beta testing on Feb 26, is now supported as a paravirtualized guest on x86 and x64 platforms, according to the beta documentation released this week.
The version 4.5 update includes changes to the kernel that will enable customers to run current RHEL 4 workloads efficiently on RHEL 5, the first Linux distribution from the company that will host virtualization.
One source close to Red Hat said version 4 guests won't run fully virtualized on version 5 because there would be performance bottlenecks. Instead, guests will be paravirtualized, he said. That ensures they will perform well but requires the kernel to be modified, as in version 4.5.
