That's what you get when everybody is hiding abstractions in 10 layers. The same thing happens with all the layers of virtual-machines

- josteink 5y agoTo be fair you have some virtualisation stacks (like QEMU/KVM) which goes in the opposite direction: It provides VMs with drivers for purely virtual “virtio” devices (storage, network, etc) with no effort or overhead put into mimicking the mechanics of a real sas/sata/scsi device or whatever. The result is less complexity and a much more direct data-path so things should hopefully not only be more performant, but also more stable.
