  • Hyper-V BPA Update

    Posted by sumeethevans on February 27 2011, 5:37 AM. Posted in Hyper-V.

    This fixes some issues in the previous BPA and also correctly handles the new Dynamic Memory and RemoteFX features in SP1. No new rules have been added. To install the update, you must already have the Hyper-V BPA installed (http://support.microsoft.com/kb/977238). Note that both the original BPA and this update apply to Windows Server 2008 R2 and Microsoft Hyper-V Server 2008 R2.

    While I recommend you have SP1 installed, this update also applies to R2 RTM Hyper-V. A quick summary of the fixes:

    • Microsoft Hyper-V Server is no longer flagged as not being a Server Core installation
    • Some ECC RAM machines were reported as non-ECC as some non-ECC firmware RAM was being included in the check
    • We have not included the File Service role feature in the scan. The reason is that we have observed certain products (Data Protection
    • Manager as an example) legitimately creating shares for adminstrative purposes. The BPA no longer flags the presence of a file share as another role being installed. However, please do NOT use your Hyper-V machine as a general purpose file server!
    • If you have SP1 and enable RemoteFX, we won't flag the machine as uncompliant due to another role being installed.
    • In the case of Windows 7 VMs only, we have increased the permitted consolidation ratio to 12:1 and updated the BPA accordingly to check for compliance.

    As SP1 changes the minimum supported memory for Windows 7 VMs if DM is enabled, the BPA has been updated accordingly. http://support.microsoft.com/kb/2485986 is the place for all the information on the changes and the download link.

  • Linux Integration Services v2.1 Now Available

    Posted by sumeethevans on July 30 2010, 11:00 AM. Posted in Open Source /Linux stuff, Hyper-V.

    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.

    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.

  • Microsoft introduces beta support for 4 vCPUs Linux VMs

    Posted by bink on April 4 2010, 2:41 AM. Posted in Open Source /Linux stuff, Hyper-V.

    Yesterday Microsoft has finally released a (beta) version of its Linux Integration Services for Hyper-V virtual machines that support multiple vCPUs.

    Specifically, the new component introduces:

    • SMP support for Linux workloads Linux virtual machines running on Hyper-V will be able to use up to 4 virtual CPU’s
    • Timesync Linux VM’s running on Hyper-V will be able to synchronize their time with the parent partition
    • Integrated Shutdown You will be able to shut down a Linux virtual machine gracefully from the Hyper-V manager

  • Terminal Server benchmarks on vSphere 4.0, XenServer 5.5 and Hyper-V 2.0

    Posted by bink on February 16 2010, 8:02 PM. Posted in Terminal Services, Hyper-V.

    Ruben Spruijt, Technology Officer PQR and Jeroen van de Kamp, CTO Login Consultants released phase 2 of their Virtual Reality Check project.

    This Project VRC phase 2 whitepaper focuses completely on analyzing Terminal Services (TS) workloads running on the latest generation hardware and hypervisors. While in phase 1 of project VRC VMware ESX3.5, Citrix XenServer 5.0 and Microsoft Hyper-V 1.0 were tested on a HP DL385G5 with AMD “Barcelona” processors, this whitepaper reviews vSphere 4.0, XenServer 5.5 and Hyper-V 2.0 running on HPDL380G6 with Intel “Nehalem” processor.

    Project VRC made a deliberate choice not to directly compare Hypervisors in phase 1 (and published results in separate whitepapers), the community and the vendors, logically, did. Therefore, we decided that Project VRC will release this single whitepaper for the phase 2 results, including the three hypervisors. This is also possible with Login VSI 2.1, the product independent VDI & TS benchmark, which allows the external timing and calibration of the workload, ensuring that the published results are not influenced by the potential clock drifts within the virtual machines.

  • Hyper-V Hotfix on Nehalem systems

    Posted by sumeethevans on October 17 2009, 4:26 AM. Posted in Hyper-V.

    We have just released a new hotfix for Windows Server 2008 R2 that address the issue that users were getting a bluescreen of death on Intel Xeon 5500 series processor-based computers with the following text:

    0x00000101 (parameter1, 0000000000000000, parameter3, 000000000000000c) CLOCK_WATCHDOG_TIMEOUT

    For the curious, this issue is actually caused by a bug (or in Intel terms “erratum”) that causes these processors to generate spurious interrupts.  You can read about this in the latest Intel documentation for this process series: http://www.intel.com/assets/pdf/specupdate/321324.pdf

    You can download the hotfix from here: http://support.microsoft.com/kb/975530

  • Hyper V RC: BIG BANG ANNOUNCEMENTs : 64LPS and Processor Compatibility Mode

    Posted by sumeethevans on May 21 2009, 9:05 AM. Posted in Hyper-V.

    So what's the BIG NEWS ??

    Microsoft Announces following two features now supported on Hyper V R2 which is included in the Windows Server 2008 R2 RC and Hyper V Server 2008 R2 RC released recently.

    1. 64 Logical Processor Support for Hyper-V R2!

    Very Soon we all be working with 8 Core processors in our servers increasing the Logical processor no. to 64 ( 8 Processors X 8 Cores ).  So now Microsoft Hyper V Supports 64 Logical processors, now you can consolidate more Virtual Machines on a single Host.

    Hyper V Evolution from 16 Logical Processor Support to 64 Logical Processor Support:

    • Server 2008 Hyper-V                                         16 LP Support
    • Server 2008 Hyper-V +update (KB95670)             24 LP Support
    • Server 2008 R2 Hyper-V Original POR                 32 LP Support
    • Server 2008 R2 Hyper-V RC/RTM                       64 LP Support!

    2. Processor Compatibility Mode for Live Migration!

    Why do we need Processor Compatibility mode??

    The OS and applications within a VM are exposed to the processor features on that server.  However, when the VM is quick/live migrated to another server, the destination server may have a processor with a different set of features.  An OS or application may try to execute CPU features that it discovered when it was started on source host but may not be present on the destination host - resulting in a failure. 

    Now You can do the live migration of Virtual Machines from one host to another in a cluster even if the processors features sets are different (But same Family Intel-Intel, AMD-AMD)

    So far we need to have identical processors on all the nodes in our cluster for Live Migration to work, but what if other node has different feature processor. Processor Compatibility Mode comes to rescue.

    When a VM is started with processor compatibility mode enabled, Hyper-V only exposes guest visible processor features that are available on all Hyper-V enabled processors of the same processor architecture, i.e. AMD or Intel.  This allows the VM to be migrated to any hardware platform of the same processor architecture.
