TEE14 Scripted Demo 5 – Out-Of-Band File Copy

In my fight demo at TechEd Europe 2014, the topic was OOB File Copy, the ability to place a file into a VM’s storage, via the VMBus, and without network connectivity to the VM (e.g. tenant isolation).

The script does the following:

1. Cleans up the demo
2. Opens up notepad. I manually copy and paste text from a website into the file and save it.
3. Enable the Guest Service Interface for the VM to enable OOB File Copy
4. Copy the file to the VM
5. Disable Guest Service Interface
6. Connect to the VM. I manually log in and open the file to verify that the file I created is now inside of the VM
7. Clean up the demo

function KillProcess ($Target)
{
    $Processes = Get-Process
    Foreach ($Process in  $Processes)
    {
        if ($Process.ProcessName -eq $Target)
        {
            Stop-Process $Process
        }   
    }
}
