Importing a VM with a snapshot from VMware to RHV results in VM having pre-snapshot data.

Solution In Progress - Updated -


  • Red Hat Virtualization 4.3 and 4.4


  • Importing a VM with a snapshot from VMware to RHV results in VM having pre-snapshot data.
  • After the import, the VM is booted and it contains older data.
  • The data is from before the snapshot.


  • BZ 1943656 has been filed to address this issue.
  • The recommended workaround is to delete the VM snapshots on the VMware environment before importing the VM to RHV.

Diagnostic Steps

  • From the VMware logs we see the first vmdk is created.

  • Next take a snapshot and there is test2-000001.vmdk.
