Vista - Problem with convert from WSH-script

Please, can you help me with this problem?

I am converting this script from WSH :
_____________________________________________
/ \
VirtualComputerNameS = "Windows 2000 Server"

Set objVS = CreateObject("VirtualServer.Application")
Set objVM = objVS.FindVirtualMachine(VirtualComputerNameS)

Set objGuestOS = objVM.GuestOS
objGuestOS.Shutdown()
\_____________________________________________/

to PowerShell :
_____________________________________________
/ \
$VirtComputerNameS = "Windows 2000 Server"

$VirtServerO = new-object -com VirtualServer.Application
\_____________________________________________/
..

I don't know, how to convert 4. and 6. line ( Set objVM =
objVS.FindVirtualMachine(VirtualComputerNameS) and Set objGuestOS =
objVM.GuestOS ) ?

Best way is to pipe $VirtServerO to get-member. It will show you what methods
are available.

Here's a wild wild guess (can't test it):


$VirtComputerNameS = "Windows 2000 Server"
$VirtServerO = new-object -com VirtualServer.Application
#$VirtServerO | gm
$GuestOS = $VirtServerO.FindVirtualMachine($VirtComputerNameS) | where {$_.GuestOS}
$GuestOS.Shutdown()

that you didn't pull the GuestOS property out as his VBscript example had.

Replace:With:
$GuestOS = $VirtServerO.FindVirtualMachine($VirtComputerNameS).GuestOS

Thank you for your help :-) , but it doesn't work.

After I run this script ... :
_____________________________________________
/ \
$VirtServerO = new-object -com VirtualServer.Application
#$VirtualServerO | get-member

$GuestOS = $VirtServerO.FindVirtualMachine("CcvVirtualPc002").GuestOS

Write-Host "1/3: Shutdown ..."
$GuestOS.Shutdown()

Write-Host "2/3: Sleep ..."
Start-Sleep -seconds 30

Write-Host "3/3: Startup ..."
$GuestOS.Startup()
\_____________________________________________/


.... I can see this text:
_____________________________________________
/ \
PS C:\> C:\Temp\Restart_Virtual_Machine.ps1

Can you post the output of :

1. $VirtualServerO | get-member
2. ($VirtualServerO | get-member FindVirtualMachine).Definition
3. $VirtServerO.FindVirtualMachine("CcvVirtualPc002") | get-member


# try this too
$vs= new-object -com VirtualServer.Application
$vs.FindVirtualMachine("Virtual Machine Name").GuestOS.Shutdown()


I found that there is also a boolean member called CanShutdown. You should
check
its before trying to shutdown the os.

this should work
Run this one at a prompt. (Note I removed the comment (#) symbol.) Look at the
results. This will give you guidance on how to continue as Shay and I don't
have the software you are working with so we were making guesses. (BTW, what
software is this exactly? MSVS? MSVPC? What version?)
If this command fails then all the ones after will as well. Look at the
Properties (values) and Methods (actions) returned from Get-Member.

The error this line caused was:

Exception calling "FindVirtualMachine" with "1" argument(s): "Either a required
impersonation level was not provided, o
r the provided impersonation level is invalid. (Exception from HRESULT:
0x80070542)"

This is a security credentials error. Are you doing this remotely or from the
console of your virtual server? Try it while logged in as someone with
permission to list virtual machines. There may be some arcane stuff required to
make the authentication happen, don't know at this point.

I added your commands to my script:
_____________________________________________
/ \
$VirtServerO = new-object -com VirtualServer.Application

Write-Host "1. Output for Shay Levi :"
$VirtServerO | get-member

Write-Host "2. Output for Shay Levi :"
($VirtualServerO | get-member FindVirtualMachine).Definition

Write-Host "3. Output for Shay Levi :"
$VirtServerO.FindVirtualMachine("CcvVirtualPc002") | get-member

$GuestOS = $VirtServerO.FindVirtualMachine("CcvVirtualPc002")
#.GuestOS

if ($?) {
Write-Host "1/3: Shutdown ..."
$GuestOS.Shutdown()

Write-Host "2/3: Sleep ..."
Start-Sleep -seconds 30

Write-Host "3/3: Startup ..."
$GuestOS.Startup()
}

BTW, I am using "Microsoft Virtual Server" version "1.1.604.0 EE R2 SP1"
and I am member of "Domain Admins" group. For that reason I think that
in permissions or rights is not problem.
