A Set CPU Count, Set Memory, or a Set CPU Count and Set Memory action indicates that the action failed in Recent Tasks.


When you run an action that changes the CPU count, the memory, or both, the action fails. It fails even though Power Off Allowed was selected, the virtual machine is running, and the VMware Tools are installed and running.


The virtual machine must shut down the guest operating system before it powers off the virtual machine to make the requested changes. The shutdown process waits 120 seconds for a response from the target virtual machine, and fails without changing the virtual machine.


  1. To determine if it has jobs running that are delaying the implementation of the action, check the target virtual machine in vCenter Server.
  2. Retry the action from VMware Aria Operations.
