Exploring Windows Server 2012 Hyper-V Worker Process Security

March 29, 2013

Another great blog post from Aidan Finn. If you want to get into the fine grain detail of the Hyper-V Worker Process Security, then read on!

The virtual machine worker process reside in user mode (as opposed to kernel mode) in the management OS (also referred to incorrectly as the host OS, running in the root partition you can see in this diagram). There is one VMWP.EXE for every running virtual machine. It’s a small process but it plays an important role, helping Hyper-V to manage the VM. It is responsible for coordinating all actions performed on a given virtual machine (start, stop, save, snapshot, Live Migration, etc) and is also where any device emulation happens (accessing the legacy network adapter, for instance).
