      During the Perf cycle for MTV 2.10 regression, running on version 2.10.0-21, warm migrations become stuck during the cutover phase.

      Environment details:

      • Total VMs: 200
      • Disks per VM: 2 (each 50 GB)
      • Cluster layout: 8 ESXi hosts, 25 VMs per host (5 VMs per ESXi in this run)

      Some VMs are stuck in a paused state with the following message:

      “DV is still in phase: Paused.”

      Example VM status:
