Retargeting to 4.10.0 to have enough time to investigate the solution and test it. It will also allow time to use govirtclient internally. This should be fixed in CNV v4.10.0-524. Tested again using red02 as provider with the same VMs : 1. 100 GB Sparse Thin disk of which 2GB actual size rhel76-100gb-os-only-thin migration took: 00:00:18 sec data copy speed - 111.1 MB/s 2. 100 GB Sparse Thin disk of which 35GB actual size (rhel76-100gb-30usage-thin) migration took: 00:04:59 min data copy speed -100.33 MB/s 3. 100 GB Sparse Thin disk of which 72GB actual size rhel76-100gb-70usage-thin migration took: 00:10:02 min data copy speed -116.28 MB/s those results are more reasonable then the previous: * on the previous cycle it took 2.5 mins to transfer 2GB disk, now it took 18 sec on the same data * 72 GB sparse disk faster than 35GB sparse disk , now the 35GB is faster then the 72GB as expected the average data copy speed is 100MB/s ( 800mb/s ) Version-Release number of selected component (if applicable): * Cloud10 * OCP-4.10 * OCS-4.9.1 * CNV-v4.10.0-598 * MTV-2.3.0-15 the full logs from the baseline results can be found under : https://drive.google.com/drive/folders/1IT7dKmfacIvMpyccQ593DgMQuu0vI-Ym?usp=sharing Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
