Products

• VMware Integrated OpenStack

Issue/Introduction

• Trying to create a image in VIO and it's failing with the error: Request Entity Too Large
• Glance API logs show errors similar to:
  ERROR glance.api.v2.image_data [req-########-####-####-####-############ ################################ ################################ - ################################ ################################] The incoming image is too large: The provided image is too large.: glance.common.exception.ImageSizeLimitExceeded: The provided image is too large.
• Glance API logs will show a line similar to below that contains the introspected size of the image in bytes (see virutal_size) for the request.
  DEBUG oslo_vmware.image_util [req-########-####-####-####-############ ################################ ################################ - ################################ ################################] Introspected the following properties from the VMDK {'virtual_size': '#####', 'vmware_disktype': 'streamOptimized', 'vmware_adaptertype': 'busLogic'} introspect_vmdk /usr/lib/python3.7/site-packages/oslo_vmware/image_util.py:327

Environment

7.x

Cause

The upstream documentation for Openstack (Train)  says that the default size for a Glance Image is 1 TB

https://docs.openstack.org/glance/train/configuration/configuring.html   see 'Configuring Glance Image Size Limit'

This message indicates that the introspected size exceeds this default limit.

Resolution

We can set a higher limit on the image_size_cap value for Glance.

1. Run the following command and add the following:  
   
   Note: indentation is important and it must be placed under the DEFAULT section
   
   #viocli update glance

conf:
  glance:
    DEFAULT:
      image_size_cap: "###" (new size in bytes)


2. Save the changes and wait for the pods to recreate
3. Re-test the image import.
