465 | What: Support for VMware's guest paravirtuliazation technique [VMI] will be | ||
466 | dropped. | ||
467 | When: 2.6.37 or earlier. | ||
468 | Why: 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. | ||
