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:
- Cleans up the demo
- Opens up notepad. I manually copy and paste text from a website into the file and save it.
- Enable the Guest Service Interface for the VM to enable OOB File Copy
- Copy the file to the VM
- Disable Guest Service Interface
- 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
- Clean up the demo

$Processes = Get-Process
Foreach ($Process in $Processes)

}
