Linux Integration Components for Hyper-V

by Harley Stagner on April 17, 2009

The Linux Integration Components for Hyper-V are now available on the Microsoft Download Center. The new integration components (which were available on connect.microsoft.com for a while) give Linux guests some extra Hyper-V virtualization and integration support, including:

  • Driver support for Hyper-V Synthetic devices- This means improved performance for items like disks and NICs
  • Hypercall Adapter- This translates Xen function calls (for Xen-enabled virtual machines) to Hyper-V hypercalls leading to increased performance for the guest.
  • Fastpath Boot Support- Boot devices can now take advantage of the storage Virtualization Service Consumer (VSC) to increase performance. The VSC is a component running  in the guest VM that is enables device I/O to be handled by the Virtualization Service Provider (VSP) through the VMBus. In short, this means increased performance for hard disks in Linux Guest VM’s.

As a reminder, the following Linux guests are supported in Hyper-V with a single virtual processor only.

  • SUSE Linux Enterprise Server 10 with Service Pack 2 x86 Edition

  • SUSE Linux Enterprise Server 10 with Service Pack 2 x64 Edition

  • SUSE Linux Enterprise Server 10 with Service Pack 1 x86 Edition

  • SUSE Linux Enterprise Server 10 with Service Pack 1 x64 Edition
