Window 7 as Guest OS for VDI : Max Virtual Processors Supported

June 14, 2011 Leave a comment

Looking to implement a VDI scenario with Windows 7 as the guest with a 12:1 (VP:LP) ratio ? With the launch of the SP1 for W2008R2, Microsof increased the maximum number of running virtual processors (VP) per logical processor (LP) from 8:1 to 12:1 when running Windows 7 as the guest operating system for VDI deployments

Formula :  (Number of processors) * (Number of cores) * (Number of threads per core) * 12

 Virtual Processor to Logical Processor2 Ratio & Totals

1Remember that Hyper-V R2 supports up to a maximum of up to 512 virtual processors per server so while the math exceeds 512, they hit the maximum of 512 running virtual processors per server.

2A logical processor can be a core or thread depending on the physical processor.

  • If a core provides a single thread (a 1:1 relationship), then a logical processor = core.
  • If a core provides two threads per core (a 2:1 relationship), then each thread is a logical
    processor.

Virtual Machines that are misaligned

March 14, 2011 Leave a comment

For existing child VMs that are misaligned, in order to correct the partition offset, a new physical disk must be created and formatted, and the data has to be migrated from the original disk to the new one.

Important note: Both Windows 7 and Windows 2008/2008R2  create aligned partition

This problem  occurs when the partitioning  scheme used by the host OS doesn’t match the block boundaries inside the LUN.If the guest file system is not aligned, it may become necessary to read or write twice as many blocks of storage than the guest actually requested since any guest file system block actually occupies at least two partial storage blocks.

All VHD types can be formatted with the correct offset at the time of  creation by booting the child VM before installing an OS and manually setting the partition offset. . The recommended starting offset value for Windows OSs is 32768. The default starting offset value typically observed is 32256.
How to verify the Offset value:

1. Run msinfo32 on the guest VM by selecting
Start > All Programs > Accessories > System Tools > System Information.
or type Start > Run and enter the following command : MSINFO32
2. Navigate to Components > Storage > Disks and check the value for partition starting offset.


If the misaligned virtual disk is the boot partition, follow these  steps:
1. Back up the VM system image.
2. Shut down the VM.
3. Attach the misaligned system image virtual disk to a different VM.
4. Attach a new aligned virtual disk to this VM.
5. Copy the contents of the system image (for example, C: in Windows) virtual disk to the new aligned virtual disk.
There are various tools that can be used to copy the contents from the misaligned virtual disk to the new aligned virtual disk:
− Windows xcopy
− Norton/Symantec™ Ghost: Norton/Symantec Ghost can be used to back up a full system image on the misaligned virtual disk and then be restored to a previously created, aligned virtual disk file system.
For Microsoft Hyper-V LUNs mapped to the Hyper-V parent partition using the incorrect LUN protocol type but with

aligned VHDs, create a new LUN using the correct LUN protocol type and copy the
contents (VMs and VHDs) from the misaligned LUN to this new LUN.

For Microsoft Hyper-V LUNs mapped to the Hyper-V parent partition using the   incorrect LUN protocol type but with misaligned VHDs, create a new LUN using the correct LUN protocol type and copy the contents (VMs and VHDs) from the misaligned LUN to this new LUN.!01

Next, To set up the starting offset, follow these steps:

1. Boot the child VM with the Windows Preinstall Environment boot CD.
2. Select

Start > Run and enter the following command:
diskpart
3. Type the following into the prompt:
select disk 0
4. Type the following into the prompt:
create partition primary align=32
5. Reboot the child VM with the Windows Preinstall Environment boot CD.
6. Install the operating system as normal.
Virtual disks to be used as data disks can be formatted with the correct  offset at the time of creation by using Diskpart in the VM. To align the virtual disk, follow these steps:

1. Boot the child VM with the Windows Preinstall Environment boot CD.
2. Select Start > Run and enter the following command:
diskpart
3. Determine the appropriate disk to use by typing the following into the prompt:
list disk
4. Select the correct disk by typing the following into the prompt:
select disk [#]
5. Type the following into the prompt:
create partition primary align=32
6. To exit, type the following in the prompt:
exit
7. Format the data disk as you would normally

For pass-through disks and LUNs directly mapped to the child OS, create a new LUN using the correct LUN protocol type, map the LUN to the VM, and copy the contents from the misaligned LUN to this new aligned LUN.

Changes specific to Windows 7 with SP1

February 24, 2011 Leave a comment

Here are the specific changes for Windows 7 SP1

1. Additional support for communication with third-party federation services

Additional support has been added to allow Windows 7 clients to effectively communicate with third-party identity federation services (those supporting the WS-Federation passive profile protocol). This change enhances platform interoperability, and improves the ability to communicate identity and authentication information between organizations.

Improved HDMI audio device performance

A small percentage of users have reported issues in which the connection between computers running Windows 7 and HDMI audio devices can be lost after system reboots. Updates have been incorporated into SP1 to ensure that connections between Windows 7 computers and HDMI audio devices are consistently maintained.

2. Corrected behavior when printing mixed-orientation XPS documents

Prior to the release of SP1, some customers have reported difficulty when printing mixed-orientation XPS documents (documents containing pages in both portrait and landscape orientation) using the XPS Viewer, resulting in all pages being printed entirely in either portrait or landscape mode. This issue has been addressed in SP1, allowing users to correctly print mixed-orientation documents using the XPS Viewer.

Windows 7 and Windows Server 2008 R2 SP1 RC. Detailed list of Improvements and others questions

November 1, 2010 Leave a comment

Microsoft has made available a Release Candidate (RC) for Service Pack 1 for Windows Server 2008 R2 and Windows 7. SP1 includes both a roll-up of operating system updates and several new capabilities for Windows Server.

Q: Can I install the Release Candidate over the Beta of SP1?
A.
 No. You must uninstall the beta.

Q: Can I install the RC on an evaluation version of Windows 7 or Windows Server 2008 R2?
A.
Yes. The RC of SP1 can install on RTM evaluation versions of Windows 7 and Windows Server 2008 R2.

Q: There are several downloads available. Which one should I choose?
A: There are two ways you can obtain the service pack RC. You can download a special key to enable Windows Update to offer you the service pack RC, or you can download the service pack directly. For each download method, you should choose the correct download for your platform (x86, IA64 or x64).

Q: Should customers who are considering deploying Windows 7 wait for SP1?
A:
No. Windows 7 is a high quality release and provides many benefits to consumers and businesses alike.  SP1 will include all updates previously available to Windows 7 users through Windows Update, so there is no reason to wait or delay their use of Windows 7.

Q. Can I upgrade from the RC builds to the final build of SP1?
A.
No. You will have to uninstall the Service Pack or do a clean install of Windows 7 or Windows Server 2008 R2.

Q. Will there be a slipstream build of SP1 RC?
A.
No. The RC will only be available as the service pack update itself. You will need to have a release to manufacturing (RTM) version of Windows 7 or Windows Server 2008 R2 to install the RC of the service pack.

Q. What languages will be released at RC?
A.
  For RC, we will release English, French, German, Japanese, and Spanish.

Q: Which improvements are included in Windows Server 2008 R2 SP1?
A. 
• Dynamic Memory – Dynamic Memory allows for memory on a host machine to be pooled and dynamically distributed to virtual machines as necessary. Memory is dynamically added or removed based on current workloads, and is done so without service interruption.
• Microsoft RemoteFX – a new set of remote user experience capabilities that enable a media-rich user environment for virtual desktops, session-based desktops and remote applications
• Enhancements to scalability and high availability when using DirectAccess – improvements have been made to enhance scalability and high availability when using DirectAccess, through the addition of support for 6to4 and ISATAP addresses when using DirectAccess in conjunction with Network Load Balancing (NLB).
• Support for Managed Service Accounts (MSAs) in secure branch office scenarios – enhanced support for managed service accounts (MSAs) to be used on domain-member services located in perimeter networks (also known as DMZs or extranets).
• Support for increased volume of authentication traffic on domain controllers connected to high-latency networks – more granular control of the maximum number of possible concurrent connections to a domain controller, enabling a greater degree of performance tuning for service providers.
• Enhancements to Failover Clustering with Storage – SP1 enables enhanced support for how Failover Clustering works with storage that is not visible for all cluster nodes. In SP1, improvements have been made to the Cluster Validation and multiple Failover Cluster Manager wizards to allow workloads to use disks that are shared between a subset of cluster nodes.

Q: Which improvements are included in Windows 7 SP1?
A. 
• Additional support for communication with third-party federation services – Additional support has been added to allow Windows 7 clients to effectively communicate with third-party identity federation services (those supporting the WS-Federation passive profile protocol).
• Improved HDMI audio device performance – Updates have been incorporated into SP1 to ensure that connections between Windows 7 computers and HDMI audio devices are consistently maintained.
• Corrected behavior when printing mixed-orientation XPS documents – Prior to the release of SP1, some customers have reported difficulty when printing mixed-orientation XPS documents (documents containing pages in both portrait and landscape orientation) using the XPS Viewer, resulting in all pages being printed entirely in either portrait or landscape mode. This issue has been addressed in SP1, allowing users to correctly print mixed-orientation documents using the XPS Viewer.

Q: Changes common to both client and server platforms:
A. 
• Change to behavior of “Restore previous folders at logon” functionality – SP1 changes the behavior of the “Restore previous folders at logon” function available in the Folder Options Explorer dialog. Prior to SP1, previous folders would be restored in a cascaded position based on the location of the most recently active folder. That behavior changes in SP1 so that all folders are restored to their previous positions.
• Enhanced support for additional identities in RRAS and IPsec – Support for additional identification types has been added to the Identification field in the IKEv2 authentication protocol. This allows for a variety of additional forms of identification (such as E-mail ID or Certificate Subject) to be used when performing authentication using the IKEv2 protocol.
• Support for Advanced Vector Extensions (AVX) – Advanced Vector Extensions (AVX) is a 256 bit instruction set extension for processors. AVX is designed to allow for improved performance for applications that are floating point intensive. Support for AVX is a part of SP1 to allow applications to fully utilize the new instruction set and register extensions.
