Update Virtual Machine Memory operation

The Update Virtual Machine Memory operation updates the memory resources of a virtual machine (VM) created on the Microsoft Hyper-V server. This topic illustrates the actor adapter request and response and describes the elements used in the request.

Warning

The Update Virtual Machine Memory operation works only when the state of the VM is "Stopped".

The following table describes the elements for the adapter request:
