With VMware Hot Add enabled, there is no need to shut down a VM to add virtual devices. VMware Hot Add makes it possible to add a virtual CPU (central processing unit) and RAM (random access memory) on the fly.

VMware Hot Add is a feature that allows you to add virtual devices to a virtual machine while the VM is running. Want to get your skills officially validated by VMware?
