When installed in a supported Linux virtual machine running on Hyper-V, the Linux Integration Components provide:
- Driver support for synthetic devices: The Linux integration components include support for both the synthetic network controller and synthetic storage controller that have been developed specifically for Hyper-V. These components take advantage of the new high-speed bus, VMBus, which was developed for Hyper-V.
- Fastpath Boot Support: Boot devices now take advantage of the storage VSC to provide enhanced performance.
- Timesync: The clock inside the virtual machine will remain synchronized with the clock on the host.
- Integrated Shutdown: Virtual machines running Linux can be shut down from either Hyper-V Manager or System Center Virtual Machine Manager, using the “Shut Down” command.
- Symmetric Multi-Processing (SMP) Support: Supported Linux distributions can use up to 4 virtual processors (VP) per virtual machine.
- Heartbeat: Allows the host to detect whether the guest is running and responsive.
- Pluggable Time Source: A pluggable clock source module is included to provide a more accurate time source to the guest.
