[<CommonParameters>] Description
The Remove-VMAssignableDevice cmdlet removes an assignable device from a specified virtual
machine (VM). This is often used in scenarios where a physical device, such as a GPU or network
adapter, was previously assigned to a VM and needs to be unassigned.
Examples
Example 1
$params = @{
VMName = "MyVM"
InstancePath = "PCIROOT(0)#PCI(0300)#PCI(0000)#PCI(0800)#PCI(0000)#PCI(1000)"
}
Remove-VMAssignableDevice $paramsThis example removes a specific assignable device, identified by its instance path, from the virtual machine named MyVM.
Example 2
$params = @{
VMName = "MyVM"
}
$vm = Get-VMAssignableDevice @params | Where-Object { $_.ResourcePoolName -eq "GpuChildPool" }
$vm | Remove-VMAssignableDeviceThis example removes a specific assignable device, identified by the ResourcePoolName property GpuChildPool, from 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.
