With the release of Windows Server 2008 R2 SP1 and the addition of Dynamic Memory, I’ve received a few requests for the link to the latest version of the Integration Services. If you’ve upgraded to R2 Service Pack 1, you have the latest Integration Services. There are a few scenarios to consider.
Guest OS is Linux. If the guest OS is Linux and you’re running the latest Linux Integration Services 2.1, you don’t need to do anything. You have the latest. For more info, see attached.
Guest OS is Windows Server 2008 R2. If the guest OS was Windows Server 2008 R2 and you upgraded the guest to Service Pack 1, then the Integration Services were upgraded as well. (How cool is that?)
Other Supported Windows Guests: If you’re running any other supported Windows OS, then you’ll need to upgrade the Integration Services. The Integration Services ISO is included with Hyper-V. When you upgrade to SP1, the Integration Services are automatically updated as well. To upgrade the Integration Services, you need to:
1. Start the VM
2. Connect to the VM
3. Go to the Action Menu and Select the bottom menu item, Insert Integration Services Setup Disk.
4. Run the Integration Services installer and restart the VM. Done.
Q: Do the Linux Integration Services enable mouse support?
A: Mouse support is not included in the Linux integration services. However, see the read me for information on where to obtain the InputVSC driver that provides mouse support when used over a RDP connection.
Q: Is Red Hat Enterprise Linux 6.0 supported?
A: At this time Red Hat 6.0 (currently) in beta is not supported. Our goal is to work with Red Hat to back port the Hyper-V Linux integration services from kernel.org tree. However, this will only happen once our drivers are out of the staging area in the kernel. We don’t have a timeline for this yet, but will share more information on this as we continue to work with the Linux community.
Q: Did Citrix develop these drivers?
A: No. The Linux IC’s were developed by a team in the Microsoft Open Source Technology Center.
Many thanks to Hank Janssen and his team, including Haiyang Zhang and Hashir Abdi.
Q: Do I need to run the Xen kernel with the hypercall shim?
A: No, the Xen kernel is no longer used.
Q: How does this relate to the announcement of Microsoft contributing the Linux IC code under GPLv2 to the Linux kernel?
A: This package provides integration components for the distributions that we support (SLES and Red Hat). Once the IC’s that have been merged into the kernel are available in distributions, we will gradually phase out the separate IC package.
Q: Is SUSE Linux Enterprise Server 11 Service Pack 1 supported?
A: No, not yet. Now that we have RTM’d version 2.1, Novell will back port these into an update for SLES 11 SP1 which will be released by Novell in the next few months. Thereafter, customers will get the Hyper-V Linux IS’s as a part of the SLES 11 SP1 distribution. No separate download or installation will be required.
Q: Will these capabilities be contributed into the mainline Linux kernel?
A: Yes, we will submit patches with these capabilities to the Linux mainline kernel as well.
We are really excited to announce the availability of the Hyper-V Linux Integration Services for Linux Version 2.1. This release marks yet another milestone in providing a comprehensive virtualization platform to our customers. Customers who have a heterogeneous operating system environment desire their virtualization platform to provide support for all operating systems that they have in their datacenters. Microsoft have supported Linux as a guest operating system on our virtualization platform from the days of Virtual Server and continue to enhance our support in that regard.
The following features are included in the 2.1 release:
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: Boot devices take advantage of the block Virtualization Service Client (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 gracefully shut down from either Hyper-V Manager or System Center Virtual Machine Manager.
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.
This version of the integration services for Hyper-V supports Novell SUSE Linux Enterprise Server 10 SP3, SUSE Linux Enterprise Server 11, and Red Hat Enterprise Linux 5.2 / 5.3 / 5.4 / 5.5.
