Select the virtual memory size on the Configure Virtual Memory page.

Minimum memory size is 4MB. Maximum memory size depends on the host. The memory size must be a multiple of 4MB. The maximum for best performance represents the threshold above which the host’s physical memory is insufficient to run the virtual machine at full speed. This value fluctuates as conditions on the host change (as virtual machines are powered on or off, for example).

Select a size for the virtual memory by using the slider or by selecting the number using the up and down arrows.
