VMware pushing its standard virtualization interface in Linux kernel

Fraser Campbell tracked VMware effort to introduce several patches in Linux kernel to make it compliant to what it’s called Virtual Machine Interface (VMI), or Paravirtualization API 2.0

In the Fraser article there are a lot of interesting informations like a comment from Zachary Amsden:

Zach was asked “Why can’t vmware use the Xen interface instead?” and he responded:

We could. But it is our opinion that the Xen interface is unnecessarily complicated, without a clean separation between the layer of interaction with the hypervisor and the kernel proper. The interface we propose we believe is more powerful, and more conducive to performance optimizations while providing significant advantages – most specifically, a single binary image that is properly virtualizable on multiple hypervisors and capable of running on native hardware.
