To avoid memory overcommitment, you must reserve all of the memory allocated to each virtual machine that runs in the VSA cluster.

Power off the virtual machine before configuring the memory settings.


In the vSphere Client, right-click a virtual machine from the inventory and select Edit Settings.


In the Virtual Machine Properties window, select the Resources tab and select Memory.


In the Resource Allocation panel, select the Reserve all guest memory (All locked) check box.


Click OK.

The virtual machine's memory is now fully reserved as a measure to prevent memory overcommitment within the VSA cluster.

Repeat the same steps for all virtual machines that run in the VSA cluster.
