Back in 2006, I posted an article about how to get Glass running in a VM. The trick was to use Remote Desktop on a Glass-enabled machine to TS into a VM which is running the same OS. If the build of the OS on your workstation is different than the one in the VM, Glass won’t work.
With the release of the Windows Virtual PC for Windows 7 Release Candidate, this subject has come up again in a post from the RedmondPie.com folks. They noticed that if you enable the Integration Services in a Windows 7 VM, you’ll get Aero Glass!
This may be news, but it’s actually the same ol’ story. The reason that enabling Integration Services gives you Aero Glass is because it uses Remote Desktop technology to show you the video from the Virtual Machine. That also helps to explain why installing Vista (or a build of 7 that is different than the one on the host) doesn’t give you Glass.
Now, you might be asking yourself why – if this is true – do you not get Glass in Hyper-V while using VMConnect? After all, VMConnect uses Remote Desktop technology to show you the VM Video, too.
To explain this, I asked Ben Armstrong what was going on, just to make sure that I understood it correctly (for the record, I didn’t). Ben thought deeply for a second, and knew that the best way to explain this to me was to draw pretty pictures on my whiteboard. I’ve tried to reproduce them below1:
