CheckSystemCompatibilityInfo method of the Msvm_VirtualSystemManagementService class
Verifies whether this computer system is able to host the specified virtual machine (VM).
Syntax
uint32 CheckSystemCompatibilityInfo(
[in] uint8 CompatibilityInfo[],
[out] string Reasons[]
);
Parameters
-
CompatibilityInfo [in]
-
Type: uint8[]
An opaque blob generated by the GetSystemCompatibilityInfo method that represents either one VM or all VMs hosted by a computer system.
-
Reasons [out]
-
Type: string[]
An array of strings containing Msvm_Error instances in CIM-XML format representing warnings or error information. These strings can be passed to the FormatError method to generate error messages.
Return value
Type: uint32
This method returns one of the following values. A return of 0 (Completed with No Error) indicates the systems are compatible. A return of 32784 (Not compatible) indicates that the systems are not compatible. Any other return value indicates an error checking the compatibility information. If CheckSystemCompatibilityInfo returns either 0 or 32784, the Reasons parameter may contain more detailed warning or error information.
| Return code/value | Description |
|---|---|
|
The computer systems are compatible. Msvm_Error objects that warn about potential problems may still be returned through the Reasons parameter. |
|
The job has started. |
|
The operation failed. |
|
The user does not have the permissions required to complete this operation. |
|
The operation is not supported. |
|
The operation failed due to an unknown status. |
|
The operation did not complete due to a time-out. |
|
The operation did not complete due to a parameter that is not valid. |
|
The operation did not complete because a required service is in use. |
|
One of the systems represented is in a transitional state (for example, Starting, Stopping, Saving) or a snapshot operation is in progress. Please wait for the operation to complete and call the CheckSystemCompatibilityInfo method again. |
|
The operation failed due to an incorrect data type. |
|
The operation failed because a required system service is not available. |
|
The operation did not complete because there is insufficient memory available. |
|
The VM is using features that are not supported by the computer system. For more details, see the Msvm_Error objects returned through the Reasons parameter. |
Remarks
The GetSystemCompatibilityInfo method is used in conjunction with CheckSystemCompatibilityInfo to determine whether a quick or live migration of a VM to another hosting computer system is possible without first trying the migration. For more details, see the Remarks section of GetSystemCompatibilityInfo.
