I still have an unanswered question about moving our Rust
minimum version forwards which I'd like to get clarity
on before we commit to this, please.

So if I understood the outcome of today's call correctly,
we should hold off on the 1.83.0 bump until that version
has landed in the relevant ubuntu LTS distros (work in
progress on their side), but after that it's available
in all our target distro versions and we can take it as
our minimum supported version ?

The missing pieces before Rust can be enabled are:
- tracing (posted, needs rebase)
- CI (needs Meson bugfixes)
- dtrace support (stap)
- lock-free MMIO and required support for Migratable<Mutex<...>>

Since Rust 1.83 is a requirement for most of the changes that are in
this pull request, holding off on it would basically mean that any
further Rust changes have to be developed out of tree. Since the above
list is not short, won't even be completed in 10.2 in all likelihood,
and doesn't include other things that people may like to work on, I'd
like this development to happen in tree.

We do have to hold off on enabling Rust until 1.83 has landed in
Ubuntu but, as I mentioned
https://lore.kernel.org/qemu-devel/0c35eccb-890a-47d1-8c54-9945519f6164@redhat.com/,
it's really unlikely that this update will end up on the critical
path. Work is already in progress at
https://bugs.launchpad.net/ubuntu/+source/rustc-1.83/+bug/2120318.

In the meantime, while Rust will be enabled progressively in more CI
jobs, Ubuntu can remain the one which tests the Rust-disabled case.

It's due to patch 58 in this pull request.

It's my patch. I missed the case of "none" machine. Sorry for it.

I see Paolo already removed the problematic one in his v2 pull request.
