465What: Support for VMware's guest paravirtuliazation technique [VMI] will be
466 dropped.
467When: 2.6.37 or earlier.
468Why: With the recent innovations in CPU hardware acceleration technologies
469 from Intel and AMD, VMware ran a few experiments to compare these
470 techniques to guest paravirtualization technique on VMware's platform.
471 These hardware assisted virtualization techniques have outperformed the
472 performance benefits provided by VMI in most of the workloads. VMware
473 expects that these hardware features will be ubiquitous in a couple of
474 years, as a result, VMware has started a phased retirement of this
475 feature from the hypervisor. We will be removing this feature from the
476 Kernel too. Right now we are targeting 2.6.37 but can retire earlier if
477 technical reasons (read opportunity to remove major chunk of pvops)
478 arise.
479
480 Please note that VMI has always been an optimization and non-VMI kernels
481 still work fine on VMware's platform.
482 Latest versions of VMware's product which support VMI are,
483 Workstation 7.0 and VSphere 4.0 on ESX side, future maintainence
484 releases for these products will continue supporting VMI.
