Comment 1 for bug 1789340

Attaching nova compute logs,

nova boot failed due to error in creating snapshot in ESXi server, as a vmdk by same name already exist in the datastore.

FileAlreadyExistsException: Cannot complete the operation because the file or folder [datastore-nfs] vmware_base/af47c1eb-0285-4fd4-87eb-079539e94726/af47c1eb-0285-4fd4-87eb-079539e94726.1.vmdk already exists.
