Public bug reported:
Scenario A:
1. image disk type: sparse
2. image size(2.3G)
3. flavor1(root_disk: 5G)
4. use_linked_clone
Scenario B:
1. image disk type: sparse
2. image size(2.3G)
3. flavor2(root_disk: 6G)
4. use_linked_clone
I boot an instance with sparse image disk, image size is 2.3G, Nova
flavor root disk is 5G, everything got well(Scenario A).
Then I boot another instance with new flavor root disk 6G(Scenario B), it
raises error:

Because the cache_image_folder already exists, it not update image size. In
_use_disk_image_as_linked_clone function, root_gb greater than image file size,
so it excutes _extend_virtual_disk error.

Title:
VMware: Extending virtual disk failed with error: capacity
Status in OpenStack Compute (nova):
New
Bug description:
Scenario A:
1. image disk type: sparse
2. image size(2.3G)
3. flavor1(root_disk: 5G)
4. use_linked_clone
Scenario B:
1. image disk type: sparse
2. image size(2.3G)
3. flavor2(root_disk: 6G)
4. use_linked_clone
I boot an instance with sparse image disk, image size is 2.3G, Nova
flavor root disk is 5G, everything got well(Scenario A).
Then I boot another instance with new flavor root disk 6G(Scenario B), it
raises error:
