Blueprint: hyper-v-wmi-v2 The Hyper-V APIs are mainly based on WMI. The original 2008 Hyper-V release introduced the "root\virtualization" namespace which got superseded in Hyper-V Server / Windows Server 2012 by the "root\virtualization\v2" namespace (referred as V2 in the sources). The original namespace has been dropped in the upcoming Hyper-V 2012 R2 (currently available in preview), which means that the Grizzly code will not be compatible with it as is. The Hyper-V driver is structured with a clear decoupling between OS interaction classes (so called *utils modules and classes) and the agent's logic. This allows us to provide an implementation of the V2 API without impacting the rest of the agent's code, based on a factory module added to instantiate the proper version of the *utils classes: the original "V1" ones for versions of the OS predating 2012 and the newer "V2" ones starting from Hyper-V 2012 (Windows kernel version 6.2).
