I am confused to why I have different information based on where I try to retrieve it from. I have 3 Windows 2012 servers (G0, G1, and G2) running Hyper-V. The following situation is captured from one server which I use to run scripts and control the others.

What I'm trying to do is to get a list of the virtual machines in existence on these 3 machines:

Using PowerGUI and PowerShell ISE:

PS > Get-VMHost | select name

Name

G0.nothing.com                                                                       
G2.nothing.com                                                                           
G1.nothing.com                                                                           


PS > Get-VMHost | Get-VM | select name

VM1628856-6                                                                                        
VM1628856-3

My main concern is that I don't have reliable information from the 3 tools. The Hyper-V Manager application shows the same list as the PowerShell does. But if I run my scripts from the other two tools, which is what I mostly do, I don't have the same information available, therefore I can't manipulate the same VMs.

I've also noticed that the Virtual Machine Manager shows the same list of VMs as the first two tools, PowerGUI and PowerShell ISE.

Which information is valid? And how can I retrieve the correct list of VMs?

EDIT 1

The $env:psmodulepath value:

PS > $env:psmodulepath
C:\Users\administrator\Documents\WindowsPowerShell\Modules;
C:\Windows\system32\WindowsPowerShell\v1.0\Modules\;
C:\Program Files (x86)\Microsoft SQL Server\110\Tools\PowerShell\Modules\;
C:\Program Files\Microsoft System Center 2012\Virtual Machine Manager\bin\Configuration Providers\;
C:\Program Files\Microsoft System Center 2012\Virtual Machine Manager\bin\psModules\;
C:\Program Files (x86)\QLogic Corporation\QInstaller\Modules

EDIT 2

PowerShell is using this Hyper-V module: C:\Windows\Microsoft.Net\assembly\GAC_MSIL\Microsoft.HyperV.PowerShell\v4.0_6.3.0.0__31bf3856ad364e35\Microsoft.HyperV.PowerShell.dll

And PowerGUI is using this one: C:\Windows\System32\WindowsPowerShell\v1.0\Modules\Hyper-V\Hyper-V.psd1

If I try to load the module used by PowerShell onto PowerGUI I still get the same different results.

How can I receive the correct information listed under Hyper-V using PowerGUI or PowerShell ISE?
