457What: Support for VMware's guest paravirtuliazation technique [VMI] will be
458 dropped.
459When: 2.6.37 or earlier.
460Why: With the recent innovations in CPU hardware acceleration technologies
461 from Intel and AMD, VMware ran a few experiments to compare these
462 techniques to guest paravirtualization technique on VMware's platform.
463 These hardware assisted virtualization techniques have outperformed the
464 performance benefits provided by VMI in most of the workloads. VMware
465 expects that these hardware features will be ubiquitous in a couple of
466 years, as a result, VMware has started a phased retirement of this
467 feature from the hypervisor. We will be removing this feature from the
468 Kernel too. Right now we are targeting 2.6.37 but can retire earlier if
469 technical reasons (read opportunity to remove major chunk of pvops)
470 arise.
471
472 Please note that VMI has always been an optimization and non-VMI kernels
473 still work fine on VMware's platform.
474 Latest versions of VMware's product which support VMI are,
475 Workstation 7.0 and VSphere 4.0 on ESX side, future maintainence
476 releases for these products will continue supporting VMI.
