Steps to Reproduce:

  1. default value of QCOW_OVERHEAD_FACTOR is 1.1

75ee426 vdsm/storage/blockVolume.py (Fred Rolland 2015-09-17 17:18:16 +0300 44) QCOW_OVERHEAD_FACTOR = 1.1

3cbc0c0 lib/vdsm/storage/blockVolume.py (Vojtech Juranek 2019-07-11 22:32:11 +0200 347) alloc_size = int(initial_size * c)

the default QCOW_OVERHEAD_FACTOR is a little waste of storage if they create a 1 TB disk (1.1 TB is assigned)
