Enabling CPU Hot Add and Memory Hot Plug

Adding CPU and memory resources to a virtual machine is a simple process. The process to add resources to a virtual machine is to power down the virtual machine, increase the number of vCPUs or amount of memory, and power on the virtual machine again.

In vSphere 4.0, two new features, CPU Hot Add and Memory Hot Plug, were introduced to allow for virtual machine vCPUs and virtual machine memory to be increased without requiring for the virtual machine to be powered off. CPU Hot Add and Memory Hot Plug must first be enabled on the virtual machine, which does require it to be powered off. Once enabled, however, CPU and memory resources may be added dynamically; powering off the virtual machine is not necessary.

How to do it…

Perform the following steps to enable vCPU Hot Add and Memory Hot Plug for virtual machines:
