Project Stratos deliverables and STR-9

by Stefano Stabellini

Hi all, I am writing this email in regards to Project Stratos following up on Mike's suggestion to clarify the deliverables. Project Stratos has three main deliverables: 1) type-1 hypervisor boot orchestration 2) VMM with safety island and Trust Zone components 3) refactored, optimized virtio We had a few discussions on the topics and I think we are all on the same page, but I thought it would be good to expand a bit on them and also get in your feedback on 3). 1) corresponds to STR-10. In the short term it means adding system device tree support for static hypervisors with a reference implementation in Xen. It involves adding support for virtual machines to the system device tree specification, and implement the specification in Xen. 2) corresponds to STR-11. The current wording is a bit confusing. We haven't settled on whether it should be based on Zephyr or based on Rust. I don't have a strong opinion either way but I have a preference for Zephyr. In any case, 2) is about having a non-Linux dom0 environment that can boot on the Cortex-As or out-of-cluster on the Cortex-Rs/Ms (to monitor VMs running on the Cortex-As.) 3) is about addressing some of virtio's limitations particularly evident with type-1 hypervisors. In the short term it means getting Virtio to run well with a type-1, Xen being the reference. In particular, this deliverable is expected to enable virtio backends to run well in an unprivileged virtual machine environment. (Today, the virtio backends have to run in an environment with privileges over the entire system.) 3) is supposed to correspond to STR-9, but actually I don't think STR-9's description matches the virtio deliverable that we have under Stratos. It looks like STR-9 comes from LBI-24, not from LBI-40. If my understanding is correct, should we create a new STR Jira ticket to cover 3)? Cheers, Stefano

Interesting QEMU thread on Rust

by Alex Bennée

Hi, People on this list might be interested on a thread currently being discussed on qemu-devel: From: Stefan Hajnoczi <stefanha(a)gmail.com> Date: Thu, 6 Aug 2020 11:24:13 +0100 Message-ID: <CAJSP0QWF8g7r5VqU_PRbskWZU3ahCq+eobR8GexUcPrAiYoCPQ(a)mail.gmail.com> Subject: Why QEMU should move from C to Rust (clickbait alert ;)) Or via: https://lists.gnu.org/archive/html/qemu-devel/2020-08/msg00800.html One of the interesting parts of the discussion was the idea of writing more device emulation in Rust. This is an idea that has been talked about before but Stefan did point me towards: https://github.com/slp/qsd which is a vhost-user storage daemon written in Rust. It uses a couple of support libraries: https://github.com/slp/vhostuser_rs https://github.com/slp/vhost-user-blk There is discussion about if the QEMU project should host these in a separate repository (so not attached to the main qemu code base) but as a reference source of vhost-user daemons. I'm going to have a play and see if they build on standard distro Rusts and how quickly I can parity match my rpmb daemon. -- Alex Bennée

Re: [Stratos-dev] Stratos Project Sync call

by Stefano Stabellini

Given that Matt has a clash and that Azzedine and I are both on the West Coast, 2PM doesn't look like a great slot. If the Linaro all hands is not every week we could do it on alternative weeks, or find another slot that works better (I have a few open at 8AM/9AM California time)?
