Considerations for OpenStack Replication


Before you configure replication for virtual machines, consider any restrictions or hypervisor-specific issues that might affect replication operations.

General Considerations

  • During a replication operation, you can only modify destination network settings for Windows VMs. Linux VMs are replicated without network connections.

  • If you select a specific VM for replication, the GUID of the source VM is used to identify the VM for replication. If the GUID of the source VM changes, the VM is not replicated. This situation can occur when a VM with the same name is added on the hypervisor for the source VM. To resolve this issue, remove the VM from the replication group and then add it back.

OpenStack Considerations

For OpenStack replication, only cinder volumes are replicated at the destination site. The destination instance is deployed only when you perform a failover operation.
