Fixed In Version: openstack-nova-2014.2.3-45.el7ost
Doc Type: Bug Fix
Doc Text:
Cause: VMware guests would be cloned when resizing an instance using the vmwareapi backend. Consequence: As a result of cloning the underlying VMware guest volumes would be copied across datastores and ephemeral disks placed on inaccessible datastores. Fix: To correct this vmwareapi now resizes the VMware guest in place without cloning. Result: Resizing instances no longer clones the underlying VMware guest leaving volumes and ephemeral disks in place. Note: To upgrade to this version please ensure no active resize operations are in progress.

Description Lee Yarwood 2015-11-23 11:50:41 UTC 
Description of problem:

An instance resize using vmwareapi leads to the associated instance VM being cloned. This in turn copies any attached volume vmdk files into instance instead of using a shadow VM that itself can be stored on a separate datastore to the instance.

This issue and many others relating to the cloning of the VM during a resize were addressed in Kilo by the following change :

How reproducible:
Always.

Steps to Reproduce:
1. resize vmwareapi instance.


Actual results:
VMWare VM is cloned causing any attached volume vmdk files to be copied into the instance instead of using a shadow VM.

Expected results:
VMWare VM is not cloned and only resized.
