"VMware Inc.'s new desktop virtualization program, VMware
Workstation 6, arrived on May 9 with support for the company's open
paravirt-ops, a virtualization performance optimizer, which as of
the 2.6.20 kernel, is now part of Linux.
"According to the company, paravirtualized Linux operating
systems are modified operating systems specifically optimized to
run in a virtual environment. Unlike current paravirtualization
technologies, paravirt-ops enables transparent paravirtualization.
This allows users to run the same Linux kernel in paravirtualized
mode on a hypervisor as well as on native hardware. As a result,
organizations have to support and maintain fewer Linux kernels,
saving management costs and simplifying application
