Fixed In Version: virtio-win-prewhql-0.1-67
Doc Type: Bug Fix
Doc Text:
Cause: Drivers and drivers' components are built now with Visual Studio. This is due to the change in Windows 8 DDK that had removed command line build tools from DDK. Old "source" files (similar to make files) where converted to Visual Studio projects. Automatic conversion set wrong calling convention for 32bit binaries of the netsh plugin that we are building and therefore it couldn't be registered with netsh and used. Consequence: All netsh plugin command line options where unusable on 32bit OSes. Fix: Change the calling convention. Result: netsh plugin is usable again. Please refer to readme.doc in the driver package directory for its usage.

Hi Min,
Could you please check how it works in build 62 and 64?
You don't need to install the drivers, just grab netkvmco.dll from
these builds and try running them.

Thank you.

This functionality is must for server OSes only. Can be moved to lower priority.
