Description

The Add-VMAssignableDevice cmdlet assigns a physical device to a specified virtual machine (VM). This is commonly used for tasks such as attaching GPUs or network adapters directly to a VM to enhance performance for specific applications or workloads. The device can be specified through its instance path, location path, or assignable device object.

Examples

Example 1

Add-VMAssignableDevice -VMName "MyVM" -InstancePath "PCIROOT(0)#PCI(0300)#PCI(0000)"

This example attaches a physical device, identified by its instance path, to the virtual machine named MyVM.

Parameters

-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
