Microsoft-om poskytnutá na takúto implementáciu plná podpora. Tieto komponenty poskytujú nasledovné funkcie (pričom to funguje aj na nepodporovaných edíciach Linuxov - pozn. autora) :
  

• Driver support for synthetic devices: The Linux Integration Services support the synthetic network controller and the synthetic storage controller that were developed specifically for Hyper-V.
• Fastpath Boot Support for Hyper-V: Boot devices now take advantage of the block Virtualization Service Client (VSC) to provide enhanced performance.
• NEW:Timesync: The clock inside the virtual machine will now remain synchronized with the clock on the host.
• NEW:Integrated Shutdown: Virtual machines running Linux can now be shut down from either the Hyper-V Manager or the VMConnect application using the “Shut Down” command.
• NEW:Symmetric Multi-Processing (SMP) Support: Supported Linux distributions can now properly use up to 4 virtual processors (VP) per virtual machine.
• NEW FOR RC: Heartbeat: Allows the host to detect whether the guest is running and responsive.
• NEW FOR RC: Pluggable Time Source: A pluggable clock source module is included to provide a more accurate time source to the guest.
