Setting up Hyper-V with a UPS

People have asked me how you go about setting up a UPS (Uninterruptable Power Supply) with Hyper-V.  This is much easier than it sounds.  The first thing to understand is that when you shut down the physical computer, the virtual machines will be automatically put into a saved state.  Virtual machines that were running when… Read more

Hyper-V Management + Delegated Administration + SCVMM

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.
