  • I’m somewhat confused what you’re asking here. The two technologies that you mentioned do not provide the ability to share a PCIe device to my knowledge which is what I understand you wish to do. The first allows network cards to directly access host memory and perform data transfers without consulting the CPU while the other allows for the sharing of a PCIe root or bus, not allowing multiple systems to access the same hardware device at the same time.

    I’ve heard of proprietary solutions, which makes sense because if you want to virtualize multiple instances of one physical hardware device I don’t see how you can do that efficiently without really intimate knowledge of device internals. You have to have separate state for these things, and I think that would be really challenging to do for an open source project.

    Anyway, just thought I would open up the discussion because I didn’t see any other comments. I hope to learn something.





  • I still have drawings I made in MS Paint on Windows 95 when it had just come out, my first text document, and the first report I ever typed in grade school.

    Btrfs snapshots of the root volume in RAID1 configuration with 8 hourly, 7 daily, 3 weekly, and automated rsync backups to NAS, with primary and secondary offsite, physically disconnected backups stored in sealed, airtight, and waterproof containers at two different banks prepaid storage and with advanced directive in the event of my demise.

    Bit of a hobby really. I acknowledge it’s completely unnecessary. I don’t like to lose data.




  • I didn’t see a brief description for this community, so please excuse me if I’m off topic.

    Small victories: I set up my first containerized WordPress application with the whole nine yards. Object cache, DB, PHP, web server in separate containers connected together by a simple and readable compose file. The task was easy. What was hard was changing the way I think about running a server as this monolithic thing. True, it’s all on one physical server in the end, but the changes in mindset are becoming more difficult for me as I get older. I had always hated Docker as this wasteful oxymoronic “serverless” thing, but then I saw how I could use it to control dev environments. From there I’ve started to understand when the tool makes sense. For the first time, I feel like I get it.
