Right, at least not yet - could you clarify the folliwing please:

So IIUC you see several issues, right?

With 762faee5a2678559d3dc09d95f8f2c54cd0466a7 you see networking issues.

With ebcce492636506443e4361db6587e6acd1a624f9 you see crashes.

I just want to make sure the issue is virtio specific and then we can drop
Linus et al and move this to the virtio ML.

Thanks!
