VMware Adds Linuxs Paravirt-ops Virtualization
VMware 6 implements native Linux virtualization technologies and improves its overall Linux compatibility. (Linux-Watch)VMwares new desktop virtualization program, VMware Workstation 6, arrived on May 9 with support for the companys 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 development.
Some virtualization solutions, such as XenSources Xen, require a Xen-enabled Linux kernel to run, but can only run a native, non-Xen Linux kernel as a virtual machine. XenSource will eventually support paravirt-ops in Xen, but it hasnt done so yet.
