LatencySensitivity
Specification of the latency-sensitivity information.
The latency-sensitivity is used to request from the kernel a constraint on the scheduling delay of the virtual CPUs or other resources. This allows latency-sensitive applications(e.g. VOIP, audio/video streaming, etc.) to run in a virtual machine which is configured to use specific scheduling latencies and to be scheduled with low latency.
The kernel does not provide any guarantee that it will meet the latency-sensitivity requirement of a virtual machine CPU or other resources but it will always accept the latency-sensitivity value provided.

Enumeration of the nominal latency-sensitive values which can be used to specify the latency-sensitivity level of the application.
In terms of latency-sensitivity the values relate: high>medium>normal>low.
Possible values:
low
: The relative latency-sensitivity low value.normal
: The relative latency-sensitivity normal value.This is the default latency-sensitivity value.
medium
: The relative latency-sensitivity medium value.high
: The relative latency-sensitivity high value.custom
:Deprecated as of vSphere API Ver 6.0. Value will be ignored and treated as "normal" latency sensitivity.
The custom absolute latency-sensitivity specified in sensitivity property is used to define the latency-sensitivity.
When this value is set to level the sensitivity property should be set also.
Deprecated as of vSphere version 5.5, this field is deprecated.
The custom absolute latency-sensitivity value of the application.
This value will be used only when the latency-sensitivity level property is is set to custom
. It is ignored in all other cases.
The unit of this value is micro-seconds and the application is more latency sensitive when this value is smaller. For example, if the absolute latency-sensitivity is 2000us, the kernel will try to schedule the virtual machine in a way so that its scheduling latency is not more than 2ms.
