Some friends here on the Hyper-V team shared a PowerShell 2.0 script for shutting down your VMs:
# Shutdown a Virtual Machine (requires Integration Components) param( [string]$vmName = $(throw "Must specify virtual machine name") ) # Get the VM by name and request state to change to Enabled $vm = gwmi -namespace root\virtualization Msvm_ComputerSystem -filter "ElementName='$vmName'" # Get the associated Shutdown Component $shutdown = gwmi -namespace root\virtualization ` -query "Associators of {$vm} where ResultClass=Msvm_ShutdownComponent" # Initiate a forced shutdown with simple reason string, return resulting error code return $shutdown.InitiateShutdown($true,"System Maintenance")
# Shutdown a Virtual Machine (requires Integration Components)
param( [string]$vmName = $(throw "Must specify virtual machine name") )
# Get the VM by name and request state to change to Enabled $vm = gwmi -namespace root\virtualization Msvm_ComputerSystem -filter "ElementName='$vmName'"
# Get the associated Shutdown Component $shutdown = gwmi -namespace root\virtualization ` -query "Associators of {$vm} where ResultClass=Msvm_ShutdownComponent"
# Initiate a forced shutdown with simple reason string, return resulting error code return $shutdown.InitiateShutdown($true,"System Maintenance")
