Powershell - Return the template name of a running VM

Which version of the PowerShell module are you running?

I'm using the 8.0 modules

Since I don't have an 8.0 environment handy, I hesitate to give you untested code, though I can tell you what you're looking for. The 8.0 powershell module will require some reflection to get at this property. We exposed this property in the 8.5 module.

The QVWComputer object returned by cmdlets such as Get-QVWComputer has a non-public backing object called the BusinessObject. This is where you will need to use reflection to gain access.

This BusinessObject has a public property named Template which has a great deal of information that might prove useful to you.

I don't have any knowledge about reflection, but google helped me with it :)

But I don't see the public property Template in the Businessobject.

I tried this:

$machines = Get-QVWComputer -Filter{$qvwcomputer.ComputerGroupName -eq $ComputergroupName} -Farm $Farmname

$machines[0].GetType().GetProperties([System.Reflection.BindingFlags]::Instance -bor [System.Reflection.BindingFlags]::NonPublic) | Where-Object {$_.Name -eq "BusinessObject"}

Did I do something wrong?

haha..nice puzzle :)

I get only the following public properties. I am missing the template

MemberType

Name

DeclaringType

ReflectedType

MetadataToken

Module

PropertyType

Attributes

CanRead

CanWrite

GetMethod

IsSpecialName

CustomAttributes

Ok, that's good, so go ahead and grab that BusinessObject and access its Template property.

I'm not 100% certain, so if it doesn't let you do that directly, it may require another level of reflection to get it out.

What are the properties that you do see? If you take out the final Where-Object clause, what is the output?

filtermaps

BusinessObject

BackingObject

Right, ok, that's the System.Reflection.PropertyInfo that the GetProperties() reflection returned.

You can use that to actually access the object's data using .GetMethod().Invoke($machines[0], []) or something to that effect. That should invoke the Get on that property for the $machines[0] object, returning the actual BusinessObject behind the QVWComputer object.
