Driver support for synthetic devices: Linux Integration Services supports the synthetic network controller and the synthetic storage controller that were developed specifically for Hyper-V.

Fastpath Boot Support for Hyper-V（Fastpath 引导支持）: Boot devices take advantage of the block Virtualization Service Client (VSC) to provide enhanced performance.

Timesync（时间同步）: The clock inside the virtual machine will remain synchronized with the clock on the host.

Integrated Shutdown（集成关机）: Virtual machines running Linux can be gracefully shut down from either Hyper-V Manager or System Center Virtual Machine Manager.

Symmetric Multi-Processing (SMP) Support（对称多线程处理支持）: Supported Linux distributions can use up to 4 virtual processors (VP) per virtual machine.

Heartbeat（运行状态）: Allows the host to detect whether the guest is running and responsive.

Pluggable Time Source（可插入的时钟源）: A pluggable clock source module is included to provide a more accurate time source to the guest.
