P2V Prerequisites in VMM

Updated: November 1, 2013

Applies To: System Center 2012 - Virtual Machine Manager, System Center 2012 SP1 - Virtual Machine Manager

VMM requirement

Check the version of VMM that you have. You can perform P2V conversions with VMM in System Center 2012 and System Center 2012 Service Pack 1 (SP1).

ImportantImportant
As of System Center 2012 R2, you can no longer perform P2V conversions in VMM. For information about how to use an earlier version of Virtual Machine Manager to mitigate this change, see the How to perform a P2V in a SCVMM 2012 R2 environment blog.

Requirements on the source machine

The physical computer to be converted must meet the following requirements:

  • Must have at least 512 MB of RAM.

  • Cannot have any volumes larger than 2040 GB.

  • Must have an Advanced Configuration and Power Interface (ACPI) BIOS. Vista WinPE will not install on a non-ACPI BIOS.

  • Must be accessible by VMM and by the virtual machine host.

  • Cannot be in a perimeter network.

    noteNote
    A perimeter network, which is also known as a screened subnet, is a collection of devices and subnets that are placed between an intranet and the Internet to help protect the intranet from unauthorized Internet users. The source computer for a physical-to-virtual (P2V) conversion can be in any other network topology in which the VMM management server can connect to the source machine to temporarily install an agent and can make Windows Management Instrumentation (WMI) calls to the source computer.

  • The source computer should not have encrypted volumes.

    WarningWarning
    If the source computer has encrypted volumes, an offline P2V conversion may render the computer unbootable.

Supported operating systems

The following restrictions apply to P2V operating system support:

  • VMM does not support P2V conversion for computers with Itanium architecture–based operating systems.

  • VMM does not support P2V on source computers that are running Windows NT Server 4.0.

  • VMM does not support converting a physical computer running Windows Server 2003 with Service Pack 1 (SP1) to a virtual machine that is managed by Hyper-V. Hyper-V does not support Integration Components on computers running Windows Server 2003 with SP1. As a result, there is no mouse control when you use Remote Desktop Protocol (RDP) to connect to the virtual machine. To avoid this issue, update the operating system to Windows Server 2003 with Service Pack 2 (SP2) before you convert the physical computer.

noteNote
Some products listed are no longer supported or are in Extended support. After extended support ends, integration services for these operating systems will not be updated and support will not be available for any issues arising from using these operating systems in virtual machines. For more information about the end of support, see the Microsoft Support Lifecycle Index.

Requirements for the destination virtual machine host

In VMM, a host is a physical computer on which you can deploy one or more virtual machines. To run P2V conversion, you need a host on which to place the image of the source computer.

Requirements for the host server include the following:

  • The destination host during a P2V conversion must be running a supported operating system. For a list of supported operating systems, see System Requirements: Hyper-V Hosts.

  • The destination host cannot be in a perimeter network.

  • As in any virtual machine creation or migration, the destination host for a P2V conversion must have sufficient memory for the virtual machine in addition to memory that is reserved for the host operating system. By default, the amount of memory that is reserved for the host operating system is 256 MB in System Center 2012 – Virtual Machine Manager. If the host does not have enough memory, you will receive a placement error in the Convert Physical Server (P2V) Wizard.

Online and offline conversions

VMM can do an online conversion or an offline conversion.

noteNote
With both online and offline P2V conversion, VMM temporarily installs an agent on the physical source computer to be converted.

The following table lists some of the differences between the online and offline P2V conversions.

 

Category Online P2V Conversion Offline P2V Conversion

Source computer availability

The source computer continues to perform normal operations during the conversion.

The source computer is taken offline during the conversion.

Process

VMM creates a copy of local NTFS volumes and data of VSS-aware applications. VMM leverages the Volume Shadow Copy Service (VSS) to ensure that data is backed up consistently while the server continues to service user requests. VMM uses this read-only snapshot to create a VHD.

The source computer restarts into the Windows Preinstallation Environment (Windows PE), and then VMM clones the volume to a VHD. Finally, VMM restarts the source computer into the original operating system.

Compatibility

Online P2V conversion is the default for the operating systems on most physical computers.

Offline P2V conversion is the only method to reliably migrate FAT volumes, and the recommended method for converting domain controllers.

Advantages

Source computer is available throughout the conversion.

Offline P2V conversion can be the most reliable way to ensure data consistency and is the only option in certain situations (see above).
