Save-VM GuestName ?

Take a look at http://pshyperv.codeplex.com The PowerShell module there for Hyper-V management has the cmdlets for working with virtual machines.

In the above module, for discovering and manipulating Machine states:

Get-VMState
Set-VMState
Convert-VmState
Ping-VM
Test-VMHeartBeat
Shutdown-VM
Start-VM
Stop-VM
Suspend-VM

So, to answer your question, to save VM state, the cmdlet will be Set-VMState

If you don't want to use any module and write your own function using WMI, take a look at MSDN documentation for Hyper-V WMI interfaces.

Ravikanth's answer looks complicated and takes a lot of reading.. but this works for me:

Stop-VM -name vmName

Or type: Get-VM | Stop-VM -save to put all machines in a saved state.
