Environment

7.x

Cause

VIO stores the image as a VM template in the vSphere datastore by default. The md5sum value is not saved between VMDK and VM template.

See VMware Integrated OpenStack 7.2.0.1 Release Notes

Resolution

The image needs to be uploaded with this flag: –-property vmware_create_template=false

#openstack image create --disk-format vmdk --file ./xenial-server-cloudimg-amd64-disk1.img --property vmware_create_template=false image.vmdk

To download use the below command:

#openstack image save image.vmdk --file download.img

Workaround:
User can also download the image file via vshpere-client.

Example

1. Find direct_url property using the command:

openstack image show 13fe0f1e-0ee6-4dc7-8b22-b518b3320c5d

direct_url='vi://vcsa01.gslabs.local/DC/vm/OpenStack/Project (f036f4c6e5184dc2a7cbff22541c1f91)/Images/13fe0f1e-0ee6-4dc7-8b22-b518b3320c5d-vcsa01-3DSAWS

2.  Browse the datastore in vCenter and search for the image id from direct_url property and download the vmdk file.
