interest in other Unixes?
by Allison Randal 26 Jun '25

Hi all, How interested would you be in patches for Unix family operating systems other than Linux? I'm working on a prototype lightweight VMM on the Illumos Kernel and Bhyve ioctl interface, and I'm planning to reuse rust-vmm libraries where I can. I prefer to work upstream on shared libraries, but I totally understand if the focus here is Linux, and patches for other Unix family operating systems are undesirable. As a concrete example of how non-disruptive this can be, the patch I'm debating whether to submit is a 4 line substitution in vmm-sys-util, which changes [#cfg(unix)] to [#cfg(linux)]. Right now, those lines are checking for target_family = "unix", but the code in question is actually unique to Linux, and fails to compile on other Unix family operating systems (mostly due to type errors, and using features that only exist on Linux), so it really should be checking target_os = "linux" instead. The specific changes are lines 8, 17, and 19, in src/lib.rs, which determine whether to use the code in the architecture-specific 'unix' directory, and whether to use the bitflags library (which is only used by the 'unix' directory). And, line 183 in src/errno.rs testing a very specific string message as the text for libc::EBADF, which has slightly different wording on other Unix family operating systems. That simple substitution makes it possible to use both vmm-sys-util and vm-memory on Illumos (since vm-memory was only using architecture-independent parts of vmm-sys-util for temp files in tests, and nothing in the 'unix' directory). I haven't started systematically testing other rust-vmm libraries for non-Linux compatibility yet, but I expect I'll find similar patterns. (Full disclosure: I personally prefer Linux Kernel and KVM, but this is paid work, and sparks enough intellectual curiosity for me to be willing to do it.) Thanks for any thoughts, Allison

[Call for Proposals] Moving to another video conferencing app for the rust-vmm sync meeting
by Florescu, Andreea 30 Jan '24

Hey, For the past years we've been using Chime for the rust-vmm sync meeting. Chime recently added a change by which people need to be explicitly allowed to enter the meeting while the meeting is ongoing. This is inconvenient and we didn't find a way to disable it. As such, we would like to switch to another application for the sync meeting. A few features that were useful with Chime and we should probably make sure other clients also support: - possibility to use it from the browser; we shouldn't force people to install (yet another) app for the rust-vmm sync meeting - support for Linux/Mac/Windows - share screen capabilities Anything else that you think it might be useful? Please add your proposals and requirements here: https://etherpad.opendev.org/p/Videoconferencing_App_for_rust-vmm_sync_meet… Once we gather options, we can vote for the preferred application. Add your requirements and proposals by 22 January 2024. Once we have the requirements & proposals, we will make a poll to decide on the app to use by 29 January 2024. Thanks, Andreea
