The amount of memory you allocate for a virtual machine is the amount of memory the guest operating system sees.

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, for example, as virtual machines are turned on or off.


On the Memory page of the New Virtual Machine wizard, select a size in megabytes or gigabytes for the virtual memory.

You can use the slider or select the number by using the up and down arrows.


Click Next.

The Network page opens.

Select network adapters for the virtual machine.
