Unable to Add Veeam Proxy VM to Replication: Error "This virtual machine is not configured for replication"

Products

• VMware Live Recovery

Issue/Introduction

Symptoms  :

• Attempting to add the Veeam Proxy VM to a replication job fails with the error:

  "This virtual machine is not configured for replication"

• Other virtual machines can be successfully added to vSphere replication without errors.

Environment

VMware Live Site Recovery 9.x

Cause

vSphere Replication (VR) does not support virtual machines with custom disk types or non-standard file extensions (like .mvmdk or potentially Veeam's proprietary snapshot/disk format) for replication. 

Cause Validation :

•    Veeam proxy VM hard disks shows an extension with .mvmdk

 

• vSphere replication hbrsrv.log reports Veeam proxy VM is inaccessible. 

         Log path :  less /opt/vmware/support/logs/hbrsrv.log

Resolution

• Contact Veeam Support to confirm whether the .mvmdk disk format is required for the Veeam Proxy VM.

• Do not configure the Veeam Proxy VM for vSphere Replication unless the disk format is fully supported.

• VMs using unsupported disk extensions (such as .mvmdk) should not be added to replication tasks, as this may lead to failed replication attempts
