When I started debugging this issue, I had no idea how far down the rabbithole would go! A few months ago, I was writing an end-to-end test for the Nextcloud integration with OnlyOffice under NixOS, to be run in a QEMU virtual machine. Curiously, my test suffered from corrupt reads from a host folder that was mounted into the VM. That was the start of a journey that led me deep into the Linux Kernel. The circumstances under which the problem occured were very specific: a certain file, read from a host folder that was mounted into the VM, would consistently be corrupt. Specifically, this was a 12943-byte file, which inside of the VM would also be 12943 bytes, but only the first 0x3000 bytes were populated: the rest was filled with zeroes. At this point I was convinced it likely only affected a very limited set of users – but I was determined to get to the bottom of it. Plan9 Mounting a directory from the host filesystem into a QEMU VM typically happens by passing something like -virtfs local,path=/nix/store to the qemu startup command. This tells QEMU to start a smal
