5.5. Hot Plugging vCPUs
You can hot plug vCPUs. Hot plugging means enabling or disabling devices while a virtual machine is running.
Hot unplugging a vCPU is only supported if the vCPU was previously hot plugged. A virtual machine’s vCPUs cannot be hot unplugged to less vCPUs than it was originally created with.
The following prerequisites apply:
- The virtual machine’s Operating System must be explicitly set in the New Virtual Machine or Edit Virtual Machine window.
- The virtual machine’s operating system must support CPU hot plug. See the table below for support details.
- Windows virtual machines must have the guest agents installed. See Section 3.3.2, “Installing the Guest Agents, Tools, and Drivers on Windows”.
