Trying to give something back to the Community...
From Ben’s blog:
A while ago I blogged about how to allow non-administrators to control Hyper-V. You do this by editing the Hyper-V authorization store. What I failed to mention at that time was that this method does not work if you are using SCVMM to manage your Hyper-V servers.
When you start using SCVMM to manage a Hyper-V server, SCVMM creates their own authorization store to be used by Hyper-V. As long as you only use SCVMM to manage your environment – this is fine. But if you want to continue to use the Hyper-V management tools, and want to allow a non-administrator to control Hyper-V – you can do this.
All you need to do is to is follow the directions in my original post – but instead of editing “\ProgramData\Microsoft\Windows\Hyper-V\InitialStore.xml” on the system partition edit “\ProgramData\Microsoft\Virtual Machine Manager\HyperVAuthStore.xml” on the system partition.
Then everything will work correctly.
