Hello
If anyone else has struggled with sepectrum-vm on AMD graphics, where the "child virtio-pci (virtio-wl)" process dies without a descriptive error, I believe the issue is fixed here: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/2570453/2/seccomp/x86_64/video_device.policy
It doesn't cleanly apply (I assume the seccomp policies have been shuffled between files), but --disable-sandbox is there as a functioning workaround :)
Does anyone have a branch where the chromium-os upstream-info is more up to date? I can have a go myself, but didn't want to duplicate effort :)
Thanks
- Jamie McClymont

P.S. an introduction: Hi everyone!
I have just started a new job where VM isolation is necessary, and have been hoping for a way to get integrated window management across VM boundaries - it looks like this is clearly the ideal approach, and I'm already a NixOS user, so am keen to contribute :)

Thanks for the tip. :) I haven't tested with AMD graphics -- not sure if
anybody else will have.

I don't think so. Somebody was interested in updating to a more recent
Nixpkgs a few weeks ago but I don't think they got anywhere. I was
planning on doing it once I got some stuff I have locally cleaned up and
committed. If you wanted to have a go that'd be great, and I'll happily
provide any help you need. :)
In particular, if you were to run into any failures due to versions of
dependencies being too old or something, we might need to sync with
upstream Nixpkgs first. If that's the case I can prioritise getting
that done unless you'd like to try that as well -- I'd expect it to be
easier than updating chromiumOSPackages because we don't heavily modify
Nixpkgs, just add to it.

Nice to make your acquaintance! I'm Alyssa, and I'm the main person
behind Spectrum at the moment. I hope you stick around. :)
