After KVM won the race for Linux kernel inclusion over VMware and XenSource, virtualization competitors need now to rely on paravirt-ops interface.

To reach such integration, VMware has to make interopeable its own virtualization interface for Linux, Virtual Machine Interface (VMI), with paravirt-ops.

Part of the task has been already achieved with the experimental support of VMI-paravirtualized Linux guests in upcoming Workstation 6.0 / Player 2.0.

Now final part of the operation is near too, with integration of VMI adapter in upcoming Linux kernel 2.6.21 as reported by eWeek.
