New Rust Xen guest tools

yann

If we want to support Ubuntu release that are "out of standard support" but not yet EoL'd, this currently puts the oldest distro as 14.04 just for 3 months (where we're using Debian 10 currently), beating Debian 8 (released 15.04, in ELTS until June '25).

But then Rust docker image for Debian 8 and 9 have long been unavailable from Docker hub, we'd have to switch to debian:8 and hope Rust will properly work there, in this platform they apparently do not support.

But we already know at least clang is much too old to be able to build the tools, even in debian:9, see https://github.com/KyleMayes/clang-sys/issues/163#issuecomment-1875216165

So supporting such old distros would need a significant investment.

ydirson created this issue in KyleMayes/clang-sys

closed "This crate only supports `libclang` 3.5 and later" with libclang 3.8 identified #163

In Debian 10 and Ubuntu 20.04, what I see is on apt-get update on first run is:

 Certificate verification failed: The certificate is NOT trusted. The certificate issuer is unknown.  Could not handshake: Error in the certificate verification. [IP: 172.65.251.78 443]

That would look like Gitlab current SSL certificates would be depending on a root CA that only appeared in newer distros?

And on subsequent runs, then I start getting 401 replies as others reported.

Hmm interesting, that's an interesting lead indeed

Are FreeBSD guests at all a consideration for new guest tools? Windows?

olivierlambert

Answer is yes for both, and work already started and going in the right direction

yann

@forbiddenera FreeBSD support is already there, and binaries are available since v0.3.0 release. However, full support making use of Netlink (supported since FreeBSD 13.2) is not to be considered as mature yet, only due to the need to use still-unofficial patches on some dependencies -- full status here.

Windows support is also coming, but requires more work than FreeBSD did, you can follow the status of the first meaningful step (communicating collected info back to host) here. Right now a few other tasks take precedence, expect things to move forward again within a few weeks.

Awesome! Maybe I'll have to take a peek.

TBH; I personally don't care much about Windows but figured I might as well ask while asking about FreeBSD

I installed a Pop OS desktop. I noticed that the icon is missing. XOCE 8e65e. Management agent 1.0.0-proto-0.3.0 Installed using the apt repo.
`

I remember reading somewhere that the icon system was going to be overhauled. I can't remember where exactly it was part of. In this instance, I feel the Ubuntu icon is perfectly acceptable, as this is an Ubuntu-based OS.

yann

Hello @ajpri1998! Can you confirm that running this in the guest does print Pop!_OS?

xenstore read data/os_distro

yann

We just released version 0.4.0. Biggest highlight is that it is not necessary any more to have libxenstore separately installed in guests, so the new RPM is now compatible with RHEL/CentOS and similar distros.

Details to be found at https://gitlab.com/xen-project/xen-guest-agent/-/releases/0.4.0

ajpri1998

@yann
Can confirm. Also was able to upgrade to 0.4.0.

$ sudo xenstore read data/os_distro
Pop!_OS

@ajpri1998 Is it Ubuntu based or Debian? I've been debating switching to Debian from Ubuntu but I've also considered Pop.

Based on Ubuntu, which Ubuntu is based on Debian. Pop is great. It's pretty much ubuntu + faster updating Kernel + a few added features. It's still very close to Ubuntu, although they are working at separating it more with their own DE.

Icons will be easier to deal with in XO 6, so expect to have an easy way to contribute to add the icon of your choice for our new UI

@yann installed tools on Rocky 8, but how to enable them?=)
And looks the old tools not removed.

I would think

that for old tools, they still working.

Use the comparable

systemctl enable xe<TAB-Key for auto complete>

And the same for

systemctl start xe<TAB-Key for auto complete>

yep, found them.

@Tristis-Oris That's it - I thought it would not be necessary to dive into the details, as the RHEL/CentOS/etc policy is that newly installed services are not started by default (as a Debian guy I never understood why, but eh), and I assumed it would in every admin's cookbook already. Will add this together with the DEB instructions.

Thanks guys for the feedback!
