+++ This bug is a downstream clone. The original bug is: +++ +++ bug 1576862 +++ ====================================================================== Description of problem: Disk size of VM matches original Virtual Size of qcow2 image instead of Size(GB) we are defining while uploading image from "Disk Options". Version-Release number of selected component (if applicable): rhevm-4.1.11.2-0.1.el7.noarch How reproducible: Always Steps to Reproduce: 1. Upload qcow2 format image using upload option from "Disks" tab. 2. Boot VM using this disk. 3. Check disk size of VM. Actual results: Disk size is of (actual) virtual size of uploaded qcow2 format image Expected results: Disk of VM should be of virtual size of disk allocated via Size(GB) from "Disk Options" while uploading disk Additional info: Extending size of disk from rhv manager portal will correctly reflect the disk size inside guest. No issue with raw format as Size(GB) under Disk Options matches device size of VM. (Originally by Ameya Charekar)
So essentially, we are not extending the disk during upload? yet another reason why we should NOT ask for disk size during upload, IMHO. (Originally by Yaniv Kaul)
(In reply to Yaniv Kaul from comment #3) > So essentially, we are not extending the disk during upload? yet another > reason why we should NOT ask for disk size during upload, IMHO. The suggested fix is to set the disk size automatically (in upload disk dialog), using size information from the qcow header (or file size for raw images). (Originally by Daniel Erez)

Tested using: ovirt-engine-4.2.4.2-0.1.el7_3.noarch Actual result: Uploaded image with virtual size of 10G and actual size of ~210MB. After booting the vm from the disk, the virtual and actual size (both from WebAdmin and API) were ~210MB and 10G respectively. Moving to VERIFIED.
