Prerequisites for Microsoft Hyper-V checkpoint replication
The following prerequisites apply to VM replication in both standalone Microsoft Hyper-V Servers and Microsoft Hyper-V clusters:
• Required Hyper-V Server user privilege: You will be required to provide the credentials of a user for the DS-Client to access the Hyper-V Server during the replication process. Ensure that the user either (1) has administrative privilege or (2) has been assigned Full Control permission to all folders on both the source and destination Hyper-V Servers that will be used for replication.
Examples of folders for both standalone Hyper-V Servers and Hyper‑V clusters:
C:\Programdata
C:\Programdata\Microsoft\Windows\Hyper-V
Hard disk locations of virtual machines on the source and destination Microsoft Hyper-V Servers
Example of folders for Hyper-V clusters only:
C:\ClusterStorage\Volume1
• Required DS-Client user privilege: DS-Client uses the location C:\Programdata for boost message queue process communication. Ensure that the DS-Client user(s) who perform any of the following tasks for VM replication have administrative privilege or have access to the location C:\Programdata
• Create or modify a VM replication set
• Start the VM replication process by clicking Replicate Now
• Import Initial VMR Set (initial VM replication data) for offline VM replication
• Perform failover or failback
The following prerequisite applies to Microsoft Hyper-V checkpoint replication for standalone Hyper-V Servers:
• Same drive letters: The disks in the destination Hyper-V Server must have the same set of drive letters (e.g., C:\, D:\, E:\) as the source Hyper-V Server that you plan to replicate.
The following prerequisites apply to Microsoft Hyper-V checkpoint replication for Hyper-V clusters:
• Same CSV: The hard disks of highly available Hyper-V virtual machines are located in Cluster Shared Volumes (CSV). The destination Hyper-V Cluster Server must have the same set of CSV as the source Hyper-V Cluster Server. That means drive letters and paths must be identical. An example of CSV:
C:\ClusterStorage\Volume1\
C:\ClusterStorage\ Volume2\
• Virtual machine in current host: DS-Client can only replicate virtual machines from the current host of the Hyper-V cluster. To replicate a virtual machine from other nodes, first migrate the virtual machine to the current host of the cluster.
• Existing mount point of cluster: Only use the existing mount point of the Hyper-V cluster, which was established when the cluster was created. Example: C:\ClusterStorage\Volume1 Do not use additional CSV mount points because the Failover Cluster Manager will change its mount point access while deleting a virtual machine checkpoint.
• Processor compatibility (Optional): When replicating virtual machines between two Hyper-V Servers that run on different types of processors, enable the feature Migrate to a physical computer with different processor version in the Compatibility settings of the source virtual machine.
