|Sector-based cloning mechanism||Provides for faster conversion speeds by leveraging sector-based snapshot cloning as the default cloning mechanism. (If volumes are resized on target virtual machines, file-based cloning is used).|
|Image Customization||Allows modification of a virtual machine's guest operating system properties after the conversion to provide it a new operating identity (for example, a new NETBIOS name, SID, or IP address).|
|VCB image restores||Users can restore virtual machines backed up using VMware Consolidated Backup (VCB) through the VirtualCenter user interface. VCB images of any guest operating system type supported by VI3 can be restored.|
|Scheduled Conversions||Ability to schedule P2V conversion and V2V migration tasks.|
|Command Line Interface for scripting||Ability to automate conversion and migration tasks using custom scripts.|
Installation of VMware Converter Enterprise for VirtualCenter requires a connection to an existing VirtualCenter 2.5 or later server. Each installation of Converter Enterprise must be associated with exactly one VirtualCenter Server instance.
VMware Converter Enterprise for VirtualCenter consists of a server component (that can be either installed on the same system as VirtualCenter Server or on a different system); and a client component that is essentially a plug-in interface to the VMware Infrastructure Client (also known as the VI Client).
The server component of VMware Converter Enterprise for VirtualCenter can coexist with installations of the standalone VMware Converter 3.x product.
PlatformsThe server component of VMware Converter Enterprise for VirtualCenter 2.5 can be installed on the following platforms:
- Windows 2000 Server SP4 with Update Rollup 1
- Windows XP Pro SP2 (32-bit and 64-bit)
- Windows 2003 Server SP1 (32-bit and 64-bit)
- Windows 2003 Server R2 (32-bit and 64-bit)
The operating system on which the server component of VMware Converter Enterprise for VirtualCenter gets installed determines what virtual machines and third-party images can be successfully imported, exported, and reconfigured. See the table below for operating system compatibility information.

Interoperability and Supported Guest Operating Systems
VMware Converter Enterprise for VirtualCenter 2.5 supports the following sources and destinations:
Import from Physical Machines
Import from Various Third-Party
Formats and VMware Products
Export to a Virtual Machine for
VMware Hosted and Datacenter Products
Operating systems that can be imported to VI3 virtual machines using hot or cold cloning:
For conditions and limitations in importing StorageCraft ShadowProtect, Acronis True Image, and Symantec Backup Exec System Recovery images, see the VMware Converter Enterprise for VirtualCenter Administration Guide.
Support for the following guest operating systems is Experimental. VMware Converter Enterprise for VirtualCenter can clone source images containing these operating systems, but the destination virtual machine may or may not work without additional configuration after import. In particular, if the source image contains unsupported hardware, you might need to modify the configuration of the destination virtual machine before using it:
- Windows NT 3.x
- Windows ME
- Windows 98
- Windows 95
This VMware Converter Enterprise release contains the following known issues.
Powering on a Microsoft Virtual PC 2007 image containing a Windows NT guest causes a critical system error
After a successful import, a blue screen appears on startup when you use Converter Enterprise Server to import a Microsoft Virtual PC 2007 image containing a Windows NT guest to an ESX Server destination. This issue is seen consistently across all ESX Server destinations: ESX Server 3i, 3.5, 3.0 and 2.5.
Vmware Converter Enterprise Server terminates abnormally when multiple jobs are run in a short period of time
If you are running multiple heavily loaded Converter jobs in a short period of time, Converter Enterprise Server might terminate abnormally. This issue is caused by the limited availability of poll threads.
Reimporting a failed or canceled Converter Enterprise import task might fail with source in use
If you try to rerun a failed or cancelled import task immediately after cancellation or failure, Converter Enterprise might fail and report that the source machine is in use. When an import task fails or is cancelled, VMware Infrastructure Client immediately indicates this, but it takes a few minutes for Converter to remove the target virtual machine. Before trying to reimport the source machine, wait for the target virtual machine to be removed. This is indicated by the successful completion of the "Destroy Virtual Machine task" (generated by Converter Enterprise server) in the task pane of the Virtual Center client.
Converter operations to VirtualCenter fail when the source machine disk size is greater than 256 GB
When VMware Converter Enterprise tries to import a source machine containing a disk size greater than 256 GB, virtual machine creation fails. This is a Virtual Machine File System (VMFS) limitation. By default, when you create a datastore the block size limit is 1 MB. To increase the file size, create a VMFS3 datastore with a larger block size.
- VMFS2: 1, 2, 4, 8, 16, 32, or 64 MB
- VMFS3: 1, 2, 4, or 8 MB
Windows misinterprets Converter Enterprise service termination
In some instances, when you stop the Converter Enterprise service from the Windows Management console or by using net stop, Windows misinterprets the action and issues the following error message: The process terminated unexpectedly. You can ignore the error message. This is the intended Converter behavior.
Restarting VirtualCenter Server when Converter Enterprise is importing a virtual machine causes out of sync inventory
If you restart VirtualCenter Server during an import, the Recent Tasks pane does not show the running Converter tasks. The target virtual machine is unusable if VirtualCenter Server is stopped while the import task is running. You must remove the target virtual machine and reimport it.
Scheduled tasks are not run if Converter Enterprise Server is disconnected from the network at the scheduled runtime
If you have scheduled tasks cued to run and Converter Enterprise Server loses network connectivity at the time the task is scheduled, the task never runs, but remains queued. You must resubmit the task. When you submit a new task to Converter Enterprise Server, the task triggers the tool to reconnect to VirtualCenter and resets all queued or running jobs.
Workaround: Launch a Converter Enterprise wizard or view an existing task to trigger Converter Enterprise to reestablish the VirtualCenter connection. Then right-click the scheduled task and select Run.
Importing a Windows Vista source machine with invalid customization values corrupts the destination machine
The destination virtual machine issues an error message and reboots over and over if any of the following situations occur when you customize your Windows Vista source machine:
- The product key is incorrect
- The domain name or domain administrator credentials are invalid
- The domain controller is unreachable because, for example, the virtual machine has no network connectivity or the domain controller is not in the network.
Converter Enterprise Server remote agent deployment fails on Windows Vista Enterprise 64-bit systems
Converter Enterprise agent remotely hot clones the remote source to the destination managed by VirtualCenter Server 2.5. However, in the case of Windows Vista Enterprise 64-bit, the remote agent is deployed but fails to run. Therefore, these systems cannot be remotely hot cloned.
Workaround 1: Power off the remote source. Use the Vmware Converter Enterprise Boot CD to import the system by cold cloning.
Workaround 2: Turn off Windows Vista User Account Control (UAC) before beginning the remote hot clone. For more information, search on the Microsoft Web site for the "Windows User Account Control Step-by-Step Guide."
Importing a Windows Vista source with a USB device to ESX Server 3.0.x causes a critical system error
If a Windows Vista source with a USB port is imported to an ESX Server 3.0.x destination, the virtual machine issues a blue screen on first startup because the destination machine does not support USB devices.
Workaround: Remove usb.present = "TRUE" from the converted .vmx file and power on the target virtual machine.
VMware Converter Enterprise cannot read short host names
If you log in to VMware Infrastructure Client by using a short machine name for Virtual Center that is resolvable by the client machine but not by Converter Enterprise agent, the agent fails to connect to VirtualCenter. When Converter Enterprise Server tries to contact the VirtualCenter server during the remote hot clone setup, the following error message is issued: Unable to find the server . Verify that the server name is correct and then try again.
Workaround: Log in by using a fully qualified host name or IP address in VMware Infrastructure client. Alternatively, you can ensure that the short host name of the VirtualCenter Server is resolvable from the remote source.
Converter Enterprise Server crashes when a scheduled task tries to import to or export from a disconnected host in the VirtualCenter inventory
If a host source or target of a Converter Enterprise Server scheduled task is disconnected at the time the task is run, Converter Enterprise Server crashes. If you encounter this problem, restart the Converter Enterprise service from the Windows service console.
Converter Enterprise allows import of powered on hosted sources
Converter Enterprise allows import of powered on or suspended hosted sources, but this action is not supported. The tool should terminate with an error message when you try to import a Workstation 5.5 or 6.0 source machine.
Workaround: Shut down and power off the virtual machine before importing it.
Setting the firewall on Windows systems to allow incoming file share connections
To allow incoming file share connections, you must set Windows Firewall in the following cases:
- When the machine is used to host standalone images
- When the machine is used as a standalone destination
- When the machine will be remotely hot cloned
- Go to Start > Settings > Control Panel > Windows Firewall.
- Click the Exceptions tab and select File and Printer Sharing.
- Click Edit.
- For each listed port, click Change Scope and select Custom list.
- Add the range of IP addresses that need access.
- Open the Control Panel and select Administrative tools > Windows Firewall with Advanced Security.
- Double-click Inbound rules and in the list of rules, select the rule(s) for File and Printer Sharing (SMB-in).
- Select View Properties and under Properties, select Scope and select Remote IP address.
- Any IP address
- Custom list of IP addresses which need access to the file server (By default, this list contains "local subnet")
Scheduled tasks might not run if you restart VirtualCenter Server
If you restart VirtualCenter Server, scheduled tasks won't run unless you create another task before the scheduled time of the original task.
Importing an Acronis image of a system with dynamic disks fails
In some circumstances, importing an Acronis image of a system with dynamic disk fails with the following error message: Guest OS not found. VMware Converter Enterprise does not support importing system images with dynamic disks.
VMware Converter Enterprise for VirtualCenter installation wizard stops responding when mapping multiple Converter Enterprise Servers to
the same VirtualCenter Server
VMware Converter Enterprise for Virtual Center supports mapping one Converter Enterprise Server to one VirtualCenter Server. If you are installing Converter Enterprise Server and map it to a VirtualCenter Server that already has an associated Converter Enterprise Server, the installation wizard hangs. To avoid this problem, make sure to map each Converter Enterprise Server to a unique VirtualCenter Server.
Manual uninstall of VMware Converter Enterprise Agent from remote source physical machine may be required
In some cases, manual cleanup of the Converter Enterprise Agent may be required. You can uninstall VMware Converter Enterprise Agent from the Add/Remove Programs control panel on the source physical machine.
Source with mixed IDE and SCSI disks might not produce a bootable virtual machine
A source machine with both SCSI and IDE disks has the IDE disks attached to the end of the disk list. If the source machine boots from an IDE disk, the target virtual machine created by Converter Enterprise boots from the wrong disk because a VMware virtual machine looks for the first disk in the disk list. Workaround:
- Boot the imported virtual machine and press F2 to enter the BIOS
- Go to the Boot menu
- Highlight the Hard Drive row and press Enter
- Change the boot order of the disks so that the system disk is first
Sysprep deletes drive letter mappings if your task includes customization
If you choose customization options and the destination virtual machine fails at a "Please Wait" screen after the second, sysprep reboot, you will need to rerun the import without customization. This problem occurs because of a problem with Microsoft's sysprep, which has deleted the drive letter mappings, preventing access to certain files.
After customizing a virtual machine, rebooting it produces an error message that msgina.dll failed to load
See the VMware Knowledge Base article, Error: "Logon User Interface DLL msgina.dll failed to load": http://kb.vmware.com/kb/907
and the Microsoft knowledge base article, "Error Message: User Interface Failure: The Logon User Interface DLL Msgina.dll Failed to Load": http://support.microsoft.com/kb/329316
Windows NT Terminal Server (SP3) fails on boot after import
**STOP : 0x0000007B
INACCESSIBLE BOOT DEVICE
When you import some Windows NT machines with old service packs, the resulting virtual machine might fail on boot up. Converter Enterprise upgrades the virtual machine's file system during the import process, and Windows NT systems with older service packs cannot read upgraded NTFS. Workaround: Ensure that the SP on the source machine is high enough to read newer NTFS file systems (SP4 and above).
Customization not applied if virtual machine manually restarted after reconfiguration
The process for customization occurs in this order:
- Customize the virtual machine image with Converter Enterprise and wait for 100% Complete
- Power on the virtual machine
- Wait for it to reboot automatically
- Sysprep processes the customizations
- Sysprep reboots the virtual machine
- The Windows operating system loads, and the network configurations occur
Cloning dual boot systems
When hot cloning dual boot systems, you can clone only the default operating system that boot.ini points to. If you want to clone the non-default operating system, change boot.ini to point to the other operating system and reboot. Once you are booted into the other operating system you can install VMware Infrastructure Client and the Converter Enterprise Client plug-in to hot clone it.
Converter Enterprise does not distinguish between physical serial ports and virtual serial ports on the source machine
Virtual serial ports are treated as physical serial ports during the migration. For instance, if a source machine has two physical serial ports and two virtual serial ports, the import creates four serial ports on the destination machine.
Importing a Windows 2000 virtual machine fails when an OEM-type partition is selected When selecting individual volumes for a clone, with or without resizing the volumes, do not select any OEM or diagnostic partitions on the disk. The only volumes needed are the active, system, and any data partitions.
Cloning a large disk with lots of free space to an ESX Server destination fails
Selecting "Import all disks and maintain size" on the Converter Enterprise import wizard Source Data page when converting a large disk with lots of free space to an ESX Server destination can cause the import to fail. Check the logs, and if there are error messages with NFC failures, use the "Import volumes . . ." method with or without resizing.
Converter Enterprise does not support, as destinations, clusters in which the VMware DRS is set to partially automated or fully automated.
Converter Enterprise can import to a cluster only if its DRS settings are set to manual instead of automatic.
