How Proxmox VE shreds your SSDs – with details (reddit.com)
Time has come to revisit the initial piece on inexplicable writes that even empty Proxmox VE cluster makes, especially we have already covered what we are looking at: a completely virtual filesystem 1 with a structure that is completely generated on-the-fly, some of which never really exists in any persistent state - that is what lies behind the mountpoint of /etc/pve and what the process of pmxcfs created the illusion of.

Make your QEMU faster (2022) (schreibt.jetzt)
NixOS uses virtual machines based on QEMU extensively for running its test suite. In order to avoid generating a disk image for every test, the test driver usually boots using a Plan 9 File Protocol (9p) share (server implemented by QEMU) for the Nix store, which contains all the programs and config necessary for the test.
