While this may not be the best solution for all deployments, I have found that installing the hyper-V role directly on the PVS server saves a lot of time when having to perform tasks such as updating PVS target device software, Anti-Virus software that modifies the network stack, or updating physical computer network drivers.
This blog hosted on the Citrix Blog site shows exactly how to use Hyper-V to update your Vdisk images. Be sure to follow these instructions to the “T”.. Using Hyper-V to update Offline vDisks , and since the best way to get super performance out of your PVS server is to run it on a Windows Server 2008 x64 box, it just makes sense to use the same server to run the hyper-v role.
If you choose to do this, I strongly suggest adding a new directory outside of your PVS store to perform the offline maintenance. You may also choose to keep the Hyper-V services stopped when you are not using them, and finally, create a dedicated network on the Hyper-V host (maybe your management network) to assign your external network to your VM’s. Although these steps are not necessary, it will ensure that your hyper-V services never interfere with your PVS services.
I would like to know if anyone else is doing this, I currently have one production deployment and my own lab running this scenario and it really does seem to work great.
