How can I increase vCPUs via Powershell?

[xacolabril]

Good afternoon,

I want to make a PowerCLI script that allow me to increase/decrease vCPUS:

1) Stopping VM.

2) Increase or decrease vCPUs.

3) Starting VM.

Can you help me in this script?

Thank you in advance.

Best regards.

Since I'm not sure if you want to create a function for this I provided a sample script to increase the vCPU number by 1.

$vm = Get-VM <VM-name>
$vm | Stop-VM -Confirm:$false
$vm | Set-VM -NumCpu ($vm.NumCpu + 1) -Confirm:$false
$vm | Start-VM -Confirm:$false

Perhaps there should also be some logic to test if the total number of vCPU is correct (1,2,3 or 4)
