This little HowTo shows you how can you get tasks on System Center Virtual Machine Manager done, by using Windows Powershell.

Load Powershell Snapin for Virtual Machine Manager:

Add-PSSnapin Microsoft.SystemCenter.VirtualMachineManager

Create Virtual Machine:

# ------------------------------------
# Job Config
$JobGroup = "0000001" # This is used to group command by a job

# Network Config
$VirtualNetwork = "External" # Name of the Network you want the VM to connect
$VLanEnable = $true # eable VLANs

Delete (Remove) Virtual Machine:

# Config
# ------------------------------------
$VMName = "server05" # Name of the VM

# Setup Process
# ------------------------------------
$SelectedVM = Get-VM -Name $VMName

# Remove/Delete VM
# ------------------------------------
Remove-VM -VM $SelectedVM

Suspend Virtual Machine:

# Config
# ------------------------------------
$VMName = "server05" # Name of the VM

# Setup Process
# ------------------------------------
$SelectedVM = Get-VM -Name $VMName

# Suspend VM
# ------------------------------------
Suspend-VM -VM $SelectedVM

Resume Virtual Machine:

# Config
# ------------------------------------
$VMName = "server05" # Name of the VM

# Setup Process
# ------------------------------------
$SelectedVM = Get-VM -Name $VMName

# Resume VM
# ------------------------------------
Resume-VM -VM $SelectedVM

Stop Virtual Machine / Turn off Virtual Machine:

# Config
# ------------------------------------
$VMName = "server05" # Name of the VM

# Setup Process
# ------------------------------------
$SelectedVM = Get-VM -Name $VMName

# Stop / Turn off VM
# ------------------------------------
Stop-VM -VM $SelectedVM

Start Virtual Machine:

# Config
# ------------------------------------
$VMName = "server05" # Name of the VM

# Setup Process
# ------------------------------------
$SelectedVM = Get-VM -Name $VMName

# Start VM
# ------------------------------------
Start-VM -VM $SelectedVM

This is a reference how you can do some thing with Powershell in the Virtual Machine Manager. You can do a lot more, like error handling, creating virtual machines from a xml config file etc…
