This week had a lot of maintenance in it for me.  In Nixpkgs I did the
usual kernel, COSMIC and crosvm maintenance, updated Rutabaga[1] (which
should make QEMU work with wayland-proxy-virtwl again), and helped with
regressions caused by a gettext update[2].  I moved the rust-vmm
virtio-bindings crate back to including generated bindings in the crate
sources[3], which was blocking Cloud Hypervisor from being able to
update it, did some server updates, and helped figure out what to do
about a build regression I introduced in the SELinux userspace[5].  I
also kept working on the networking fixes I've mentioned previously.
They're basically done now, but I just found another bug I want to fix
first.

I attended two NGI Zero webinars.  One was about the business mentoring
services offered by the programme[6], which had a lot of immediately
useful stuff in it, and the other was about applying for EU Horizon
grants directly, which will probably be more relevant in a couple of
years but still good to start thinking about.  Demi and I also tried to
go to the KVM/QEMU community call, but were foiled by the wrong timezone
being given in the reminder email.  We did learn that despite the name,
it's mostly about QEMU anyway, so not as relevant to us as we thought.

Demi continued her heroic work fixing soundness bugs in Cloud
Hypervisor[7], but more keep presenting themselves, so there's more work to
be done yet.
