Hello, could someone explain me the purpose of stacking block devices on top of each other?
A block device with driver file or qcow2 "is usually" stacked on top of a block device with driver raw as stated in the docs[1]. The related sentence came with [2] within the batch [3]. I couldn't figure out why this 'stacking' might be useful. Thanks and kind regards, Raphael [1] Driver-specific options for raw: https://qemu.weilnetz.de/doc/latest/system/invocation.html#hxtool-1 [2] doc: Document driver-specific -blockdev option: https://lists.nongnu.org/archive/html/qemu-devel/2017-06/msg05325.html [3] [Qemu-devel] [PULL 00/61] Block layer patches: https://lists.nongnu.org/archive/html/qemu-devel/2017-06/msg05319.html -- Hetzner Online GmbH Am Datacenter-Park 1 08223 Falkenstein/Vogtland raphael.p...@hetzner.com www.hetzner.com Registergericht Ansbach, HRB 6089 Geschäftsführer: Martin Hetzner, Stephan Konvickova, Günther Müller
