Hi guys,

First off, hello :) New to the community, looks very helpful and active
indeed...

As i say, I am new to Ruby and am trying to port some WMI Powershell
code over  I am not having much luck... My goal is to automate Hyper-V
on Windows 2008, as an example at a very simple level in powershell I
can do:

## Define variable for getting VSMS class
$VSMS = get-wmiobject MSVM_VirtualSystemManagementService -namespace
"root\virtualization"
## Then call a method on that class like this. Definevirtualsystem is
the method in question, I call it with no parameters.
$VSMS.definevirtualsystem()

I have tried two libarys in Ruby, win32ole and ruby-wmi. The synatx for
ruby-wmi confused me the most, so can only post a (kind of) working
example with win32ole:

require 'win32ole'
wmi =
WIN32OLE.connect("winmgmts:\\\\localhost\\root\\virtualization:Msvm_VirtualSystemManagementService")
wmi.ExecMethod(DefineVirtualSystem())

... this gives me the following error:
test.rb:4: undefined method `DefineVirtualSystem' for main:Object
(NoMethodError)

Also one of the tricks with WMI is to get the XML output of a class,
change the settings and squirt it back.

Using the previous example, i could do:

$VSMS.psbase.gettext(1)

...to give myself the raw XML. Is there an easy way to do this in Ruby?

Any pointers would be greatly appreciated.

Cheers,

Nick
