389 | What: Support for VMware's guest paravirtuliazation technique [VMI] will be | ||
390 | dropped. | ||
391 | When: 2.6.37 or earlier. | ||
392 | Why: With the recent innovations in CPU hardware acceleration technologies | ||
393 | from Intel and AMD, VMware ran a few experiments to compare these | ||
394 | techniques to guest paravirtualization technique on VMware's platform. | ||
395 | These hardware assisted virtualization techniques have outperformed the | ||
396 | performance benefits provided by VMI in most of the workloads. VMware | ||
397 | expects that these hardware features will be ubiquitous in a couple of | ||
398 | years, as a result, VMware has started a phased retirement of this | ||
399 | feature from the hypervisor. We will be removing this feature from the | ||
400 | Kernel too. Right now we are targeting 2.6.37 but can retire earlier if | ||
401 | technical reasons (read opportunity to remove major chunk of pvops) | ||
402 | arise. | ||
403 | |||
404 | Please note that VMI has always been an optimization and non-VMI kernels | ||
405 | still work fine on VMware's platform. | ||
406 | Latest versions of VMware's product which support VMI are, | ||
407 | Workstation 7.0 and VSphere 4.0 on ESX side, future maintainence | ||
408 | releases for these products will continue supporting VMI. | ||
409 | |||
