Summary: Storage migration across cluster failing in VMWare due to
com.vmware.vim25.DuplicateName while starting the VM
Key: CLOUDSTACK-258
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-258
Project: CloudStack
Issue Type: Bug
Components: VMware
Affects Versions: pre-4.0.0
Environment: Hypervisor: VMWare 5.0
MS: RHEL6.3
Git Revision: 14486767e3c0d28f4a0f9a2ae36cfb3d1e0581a8
CloudStack-non-OSS-58
Reporter: Sowmya Krishnan
Fix For: pre-4.0.0
Storage migration across cluster is failing while starting the VM again after
migration.
Steps:
1. Stop VM
2. Detach data disk if any
3. Migrate VM to another Primary storage in another cluster
4. Once migration is complete, start VM
(I've enabled vmotion)
After migration, the root disk is migrated properly to the new primary storage.
But when VM is started, it gives the following exception and moves back again
to the original cluster.
Exception:
