IVMAccountant::SetSchedulingParameters method
The SetSchedulingParameters method sets the scheduling parameters for a virtual machine.
Syntax
HRESULT SetSchedulingParameters(
[in] VARIANT reservedSystemCapacity,
[in] VARIANT maxSystemCapacity,
[in] long relativeWeight
);
Parameters
-
reservedSystemCapacity [in]
-
Minimum percentage of system capacity that will always be available to this virtual machine. The minimum value for this parameter is 0, the maximum value depends on the number of host processors. This argument is treated as a floating-point value (that is, VARIANT of type VT_R8).
-
maxSystemCapacity [in]
-
Maximum percentage of system capacity that can be used by this virtual machine. The minimum value for this parameter is 1, the maximum value depends on the number of host processors. This argument is treated as a floating-point value (that is, VARIANT of type VT_R8).
-
relativeWeight [in]
-
Number between 1 and 10,000 representing priority of this virtual machine relative to other virtual machines. A higher number indicates a higher priority.
Return value
This method supports standard return values, as well as the following. For information on Virtual Server specific return values not listed below, see HRESULT Codes Specific to the Virtual Server.
| Return code | Description |
|---|---|
|
The operation was successful. |
|
A parameter was out of range. |
|
Unknown virtual machine. |
|
An unexpected error occurred. |
Remarks
The maximum values for reservedSystemCapacity and maxSystemCapacity depend on the number of processors on the host. For one host processor, the maximum percentage is 100. For two host processors, the maximum percentage is 50. For four host processors, the maximum percentage is 25. The reserve system capacity must be less than or equal to the maxSystemCapacity.
