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