Hyper-V Linux Integration Services 2.1 RTM
The Microsoft Virtualization Team blog has recently announced that version 2.1 of the Linux Integration Services has been released. Quoting from their website, 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. You can obtain the Linux IS’s via the Microsoft Download Center.
I’ve been told that this realease also fixes some major time drifting issues on Linux guests running with the SMP (multiprocessor) option activated that were present in the RC version. On this note, I’ll also be releasing a screencast (in Romanian) on running Linux under Hyper-V soon, along with some best practices.
