A new version (2.1) of the Linux Integration Services for Hyper-V have just been made available. This new version has some significant improvements. From the driver side, new optimized storage and networking drivers have been introduced (aka “Synthetic” drivers which utilize VMBus, a key component in the Hyper-V architecture, essential for efficient and fast device I/O without the need for emulation). Supporting VMBus allows us to boot Linux guests faster. Integration components have been added in the form of time synchronization, heartbeat monitoring and shutdown capability.
And the big one that everyone I talk to has been asking for…. up to 4-way SMP Linux guests.
