Is there anyone or going plan working on supporting of asterinas?

Hi! Friends from syswonder. I'm working on hvisor supporting of asterinas rn. I hope know the current news from syswonder community including your plans or attitude.
Thanks!

Hello, we have recently started working on hvisor support for the Asterinas kernel, and we will be pushing our progress to the dev-asterinas branch. We have now achieved booting Asterinas in zone1, but support for some virtio devices is still insufficient. Contributions to this work are welcome.

Roadmap:

• Boot Asterinas kernel in zone0
• Boot Asterinas kernel in zone1 without virtio devices
• Use virtio-console in zone1
• Use virtio-blk in zone1
• Use virtio-net in zone1
• Test on real x86 hardware
• Support Asterinas NixOS
• Support other archs (riscv, loongarch...)

So it doesn't support full regression test rn?
I've booted asterinas a few weeks ago, and supported vitio-blk nad vitio-net already passing all regression tests. But I have some trouble passing all benchmark tests.

btw: where can I keep up with this work. Is it public in some repos? I didn't find them.

Thanks! I'm in big passion working on this and related hvisor-book part! @Solicey

We have pushed the latest progess onto branch dev-asterinas, you are welcome to contribute code by submitting pull requests to this branch. By the way, you mentioned that you have booted Asterinas and supported virtio-blk and virtio-net, would you like to share more details about your work? We haven't started running full regression test yet, and it would be really helpful if you could sync your progress with us.

This is result of regresson tests, something wrong with this.But it's not a big deal. VirtIO-blk benchmark has failed, but I'm still try to know where it comes from(maybe related to memory). One thing could be confirmed is that VirtIO works rn but not perfect.

I will see your repo and see what can I do

I am quite curious about whether you are running Asterinas regression test directly on QEMU, running with hvisor on zone0, or running with hvisor on zone1. If the answer is on zone1, we might need to check implementations of hvisor-tool, since it is the provider of zone1's virtio devices.

zone1, 'Cause I'm doing benchmark between direct qemu boot asterinas and zone1 on hvisor.

Yes, I modified hvisor-tool at the same time to support this.

Thanks for the reply. I was dealing with virtio-blk recently and found it necessary to modify hvisor-tool. Pull request to hvisor-tool is also warmly welcomed.

I’d like you to define the scope of one important yet non-urgent task to prevent duplicate work between us. It’s frustrating when we develop in parallel only for one party’s work to end up unused.

I agree with that. Since you have already achieved virtio support on zone1, I might temporarily switch to other works, like testing hvisor and Asterinas on real hardwares (to be specific, ASUS NUC14 Elite). Meanwhile you can submit pull requests regarding virtio devices or any other targets.

[yydawx]

I'm OK with that!

Wait, "boot in zone1" in asterinas-zone0 or linux-zone0.
I only achieved booting zone1-asterinas on zone0-linux with virtio devices, does it make sense?

[yydawx]

Besides, could you please offer a simple guidence on how to boot asterinas as zone0 and zone1? Since there are different kinds of kernels that asterinas can make out. I tried by myself but failed. Thanks!!

Yes, "boot in zone1" means running asterinas-zone1 with linux-zone0.

Our ultimate goal is to run Asterinas on zone1, so you don't have to worry about running on zone0. I am using grub-rescue-iso as BOOT_METHOD and linux-legacy32 as BOOT_PROTOCOL to launch Asterinas on zone0.

By the way, would you like to add WeChat friends? We could discuss more conveniently on WeChat I suppose. My WeChat ID is also Solicey, feel free to contact me.
